Callers who +want everything must say `?toolsets=all`; callers who want the account tools +WITHOUT the chain reads say `?toolsets=core` (10 tools, ~2.4k). Every figure is +printed by `test/mgmt-toolsets.test.ts` on every run rather than being maintained +here; read that output, not this sentence, when the number has to be exact. + +**The default changed in SHARK-3629**, and it is the one behavioural change on +this endpoint that an existing caller can notice: a connection that names no +`?toolsets=` used to get `core` alone and now also gets the sixteen chain reads +plus `mgmt_select_key`. It only ever ADDS tools, so nothing a caller already +depended on moved, but the entry cost went from ~2.4k to ~8.8k tokens. A caller +that wants the old listing asks for it by name. + +Those are REAL o200k counts. `mgmt_list_toolsets` prints slightly larger numbers +for the same listings (~9.0k for the default and ~37.1k for all) because the +served process carries no tokenizer and estimates at four characters per token. +The estimate runs 2.6% to 10.9% high across the nine selections, measured on +every test run and gated at 15%. Same quantity, two measurement methods, and the +estimate is deliberately the one that overshoots: a caller is never surprised by +a listing that costs more than it was told. + +Four properties this parameter has, and each one is a test: + +- it only ever SUBTRACTS — `all` is exactly the pinned tool list, and every other + value is a subset of it; +- it changes nothing about a tool that IS registered. The HITL approval gate, the + second-factor policy, the `expectAccount` check and the account-scope wrapper + are per tool and are identical either way; +- it is read ONLY on `initialize`. A follow-up `POST`, `GET` or `DELETE` carrying + it is inert, so the PARAMETER cannot widen a live session, and it takes no part + in the session-identity binding (SHARK-3384); +- an unrecognised name FAILS the initialize with a 400 naming the valid set. It + does not fall back to a default, and it does not echo the value back. + +**`mgmt_load_toolset` (SHARK-3609).** A live session CAN be widened, by a tool +call on the session itself: `mgmt_load_toolset` with `toolsets=keys` (or a +comma-separated list, or `all`) registers those groups in place, emits ONE +`notifications/tools/list_changed`, and the tools appear mid-conversation. No +reconnection, no DCR re-registration, no re-authentication. That matters here +more than it would on an unauthenticated server: a reconnect re-runs the OAuth +dance, the DCR client registry does not survive a redeploy (SHARK-3547), and +every control-plane route in that dance shares one per-IP limiter, so "load one +more group" used to be able to fail in three different ways and take the working +session with it. + +The reversal is deliberate and it is not an authorization change. The selection +is a context-cost control, never a boundary: loading a group changes what is +ADVERTISED, and every tool keeps the HITL gate, the second factor and the +account scope it always had, whichever way it was registered. Both properties +are tests (`test/mgmt-load-toolset.test.ts`): the surface after loading `keys` +equals a session opened with `?toolsets=core,keys` name for name and byte for +byte, and a gated write that arrives mid-session still demands its approval. + +Groups are registered LAZILY rather than registered-then-disabled, because the +cost was measured rather than assumed: building every group costs 1.006 ms and +671 KB per session against 0.200 ms and 148 KB for `core` alone, so +register-everything-disabled would have charged every default session ~0.87 ms +and ~510 KB for tools it never lists. Against a 512Mi pod with a bounded session +registry that is a real bill. The tool itself costs `core` one extra entry: 223 +o200k tokens, 2039 → 2262 when SHARK-3609 measured it. The budget the test +asserts is on the DEFAULT selection rather than on `core`, and since SHARK-3629 +that is `core` plus `data`: 8,823 measured against an 8,900 ceiling. + +**Process memory, and what a chain-free session costs (SHARK-3635).** SHARK-3629 +made this binary import the data plane, which brought `gpt-tokenizer` with it: +65 MB and 386 ms, paid at boot by every pod whether or not a session ever read a +chain. The tokenizer now loads on FIRST USE and is warmed by `registerDataTools`, +so it arrives with the chain tools instead of with the import statement. +Measured per process, one scenario each: + +| Process | RSS | tokenizer | +| ------------------------------------ | ---------------- | ----------------- | +| `import src/mgmt/server.ts` | 118 MB (was 177) | not loaded | +| `?toolsets=core` session | 104 MB (was 176) | not loaded | +| default (`core` plus `data`) session | 176 MB | loaded | +| `/rpc` `createServer` | 170 MB | loaded, as before | + +RSS figures are one run on one machine and move with the Node build, the GC and +the transform cache: the same cold process read 118 MB locally and 149 MB on a CI +runner. Read the column as an order of magnitude, not a budget. +`test/tokenizer-lazy.test.ts` holds all four rows, one child process per row, and +asserts the MODULE LOAD rather than the megabytes, which is exact and the same +everywhere. + +This is why `mgmt_list_toolsets` still reports a chars/4 estimate rather than a +real count: it is in `core`, so counting for real would pull those 65 MB back +into exactly the sessions this relieved. + +Any session can call `mgmt_list_toolsets` (it is in `core`) for each group's tool +count, approximate token cost and reconnect URL; the same catalogue is one line +of the server instructions. + +- `GET /healthz` — LIVENESS only (`{ ok: true }`, unconditional). +- `GET /readyz` — READINESS (`{ ready, draining }`); `503` from the moment a drain starts, so a pod on its way out stops being handed sessions. On this plane a session pins a gateway credential, so one issued during a shutdown is an authenticated session that dies seconds later. +- `GET /metrics` — Prometheus exposition on a SEPARATE listener (`METRICS_PORT`, default `9464`), in-cluster only. Do not route it through the Gateway or the VirtualService: this plane's metrics name the OAuth legs, the DCR registry occupancy and the approval outcomes. +- `GET /.well-known/oauth-authorization-server`, `GET +/.well-known/oauth-protected-resource` — discovery (SDK metadata router). +- `POST /register`, `GET /authorize`, `GET /callback`, `POST /token` — OAuth. +- `GET /confirm/:token` — SHARK-3381 human approval. Starts a fresh interactive + UAuth login (NOT behind the agent bearer); `/callback` approves the bound + confirmToken only for the matching account (`unique_id`). Rate-limited. +- `POST /confirm/approve` — the approval itself: a deliberate form POST carrying + the one-time consent ticket rendered to the authenticated browser. Also + rate-limited. **It is a route in its own right and needs its own ingress / + WAF treatment** — a rule that admits `GET /confirm/*` and not this POST leaves + every HITL-gated write permanently unapprovable, with no error until a human + has already logged in. + +**CORS:** applied app-wide (browser MCP clients call the control plane + `/mcp` +cross-origin). Origin allowlist via `MGMT_CORS_ORIGINS` (defaults to +`https://claude.ai`, `https://claude.com`, `https://cursor.com`; loopback origins +on any port only when `MGMT_ALLOW_LOOPBACK_CORS=true`, which is the default in +development only); `credentials:false`; exposes `Mcp-Session-Id` + +- `WWW-Authenticate`. + +**Rate limiting:** **SIX** unauthenticated control-plane routes are behind a +per-IP in-memory token bucket (capacity 60, refill 1/sec) → `429` + +`Retry-After` on burst: the four OAuth routes (`/register`, `/authorize`, +`/callback`, `/token`) **and both approval routes** (`GET /confirm/:token`, +`POST /confirm/approve`). They share ONE bucket per IP, which is the operational +fact worth knowing: a client hammering `/authorize` from the same source address +can 429 a human's approval click, and the two are not separable without +splitting the limiter. In-memory is fine under `replicas:1` (below); move it +with the session store when that is externalized. The `/mcp` data path is +**not** limited here (callers bring their own quota'd credential). + +## Observability (SHARK-3607) + +Both planes emit the same `mcp_ankr_*` metric families with a `plane` label, and +the same structured JSON logs. `DEPLOY-RUNBOOK.md` section 9 carries the full table and the +reasoning behind the naming, the cardinality rules and the log-field allowlist; +this section records only what is specific to the management plane. + +- `mcp_ankr_refusals_total{control="rate_limit"}` is what settles SHARK-3592. + The control-plane limiter refuses with a 429 on `/register`, `/authorize`, + `/callback` and `/token`; until now nothing counted those, so "the limiter does + not limit in production" could not be confirmed or refuted. +- `mcp_ankr_refusals_total{control="dcr_cap"}` plus + `mcp_ankr_dcr_clients_live` / `mcp_ankr_dcr_client_limit` say whether the DCR + registry is full. A full registry answers `503` + `Retry-After` and refuses a + NEW client rather than evicting somebody else's, so it reads to a client as a + transient outage and needs to be visible as capacity. +- `mcp_ankr_oauth_leg_total{leg,outcome}` covers the four legs. A funnel with + only successes cannot show where clients fall out, so refusals are counted with + the same names. +- `mcp_ankr_confirmations_total{action,outcome}` measures the human-approval + gate: whether approvals are being requested at all, and whether they complete. +- The 401 on `/mcp` has three producers (the SDK's bearer middleware, the + shim-token resolution, the session-identity check), so the refusal is counted + at most ONCE per response; see `refuseOnce` in `src/mgmt-http.ts`. + +Nothing here logs a credential: the log field set is a closed allowlist, and the +UAuth bearer, the shim JWT, a TOTP and a `confirmToken` are all outside it. + +**Tool calls on this plane are counted since SHARK-3637.** They were not before, +and the reason is worth keeping: SHARK-3607 patched `registerTool` in +`createServer` only, which was complete while the data plane was the only thing +with tools. SHARK-3629 put the sixteen chain reads here too, and from that moment +the same tool name was counted when served from `/rpc` and not counted when +served from `/mcp` — silently, because nothing errors and no series disappears. +None of the ~78 management tools had ever been counted either. + +The same helper (`src/obs/toolMetrics.ts`) now runs against this server before +`registerMgmtTools`. Three things make it reach the whole surface rather than +part of it, and each is asserted in `test/obs-mgmt-tool-metrics.test.ts`: +`withAccountScope` reads `server.registerTool` at call time rather than capturing +it, so the ~70 wrapped tools go through it; the patch replaces `registerTool` on +the server INSTANCE, so a group loaded later through `mgmt_load_toolset` is +wrapped too; and the helper is idempotent per server, because both planes call it +and this one also receives the data plane's registrar. + +**This WIDENS two metric families, so anything reading them changes meaning.** +`mcp_ankr_tool_calls_total` and `mcp_ankr_tool_call_duration_seconds` will carry +management tool names that never appeared before, and volume on the sixteen +chain-read names rises because the `/mcp` share stops being invisible. Split by +`plane` where the distinction matters. Nothing narrows, so no existing series +loses data. + +## Tools (PoC) + +**94 tools are registered** on the management server (`?toolsets=all`; 75 before +SHARK-3600 added `mgmt_list_toolsets` to `core`, SHARK-3609 added +`mgmt_load_toolset` beside it and SHARK-3629 added the `data` group's sixteen +chain reads plus `mgmt_select_key`), of which **32 are HITL-gated**. +The HITL count and the classification of the **78 management** tools are held by +`test/mgmt-annotations.test.ts`, which asserts the classified sets partition the +MANAGEMENT surface exactly, so a new tool cannot land unclassified. The **16** +chain-read tools are governed by `test/annotations.test.ts` instead — the whole +chain plane is read-only and open-world, which is the opposite of what the +management rules assume — and the boundary between the two is `DATA_TOOL_NAMES` +in `src/server.ts`, pinned against the live `/rpc` surface by +`test/data-tool-surface.test.ts`. + +Note the two counts do not split the `data` GROUP down the middle by accident: +the group has seventeen members, and the seventeenth is `mgmt_select_key`, which +travels with the chain tools but acts on the session and stays in the management +partition (`isDataToolName("mgmt_select_key") === false`, asserted). `test/helpers/mgmtToolSurface.ts` is where all +94 are written out by name, split into their groups. The bullets below are the operationally interesting families, not +the inventory; `tools/list` on a live pod is. + +- `mgmt_get_usage` (SHARK-3375) — read-only; `GET /auth/intervalUsage`. +- `mgmt_create_api_key` (SHARK-3374) — state-changing; `POST +/auth/jwt/additional`. **The reply DOES carry a live credential (SHARK-3568 + corrected this bullet, which said only that `jwt_data` is never returned and + therefore read as "returns no secret").** `jwt_data`, the key's signed + material, is still never shown; what IS returned, since SHARK-3539, is the + key's **endpoint token** plus a ready `rpc.ankr.com//`, obtained + through the worker exchange described above. That token can spend the + account's paid RPC quota, so the reply belongs in the same care as a password + and the tool is HITL-gated with the consent page saying so. Same for + `mgmt_reveal_api_key`. `mgmt_list_api_keys` stays redacted by design and never + carries a token. +- **Naming a key (SHARK-3612).** The eleven tools that operate on one key — + freeze, the five allowlist writes, the three allowlist reads, the key status + read and the spending scope — take the key's **slot `index`**, as + `mgmt_list_api_keys` shows it. The shim resolves the slot to the key's endpoint + token internally (`GET /auth/jwt/all` → the worker exchange) and never emits + it: not in a result, not in `_meta`, not on the approval page, which names the + key by slot and name instead. `token` is still accepted and documented as + deprecated. This replaces a two-approval path: freezing a key you had not just + created previously required `mgmt_reveal_api_key` first, so the reversible + action required performing the credential-disclosing one, and every key an + operator touched left a live RPC credential in the transcript. The approval + binds to the RESOLVED token, so an approval minted for slot 4 cannot be spent + on slot 7 (`test/mgmt-key-addressing.test.ts`). `mgmt_reveal_api_key` is + unchanged and remains the tool for when a human genuinely wants the credential. +- Key CRUD + allowlists (SHARK-3374), usage/billing reads (SHARK-3375), + notifications (SHARK-3378), and payment initiators (SHARK-3377) are also + registered (see `src/mgmt/tools/`). +- **Platform API keys (SHARK-3574)** — `mgmt_create_platform_api_key` / + `mgmt_list_platform_api_keys` / `mgmt_delete_platform_api_key`, over + `POST /auth/token/custom/new`, `GET /auth/token/custom/all` and + `POST /auth/token/custom/delete`. Operationally these are unlike every other + credential this plane touches, so three facts matter here rather than only in + the code: (1) the minted `access_token` is a **bearer for the management API + itself**, so a holder has this whole surface with **no HITL approval and no + second factor** — it does not go through this shim at all; (2) it is returned + **once**, in the mint reply, and never enters a log, `_meta`, the consent page, + an error message or the listing, so there is no way to recover one and rotation + means mint-new-then-revoke-old; (3) none of the three routes takes `?group=` + (the console passes none), so all three **refuse** while a team account is + selected rather than answering for the credential's own account — the + per-route evidence is in `src/mgmt/gateway/groupScope.ts`. `ttl_sec` is capped + by the schema at 365 days, the longest the console's own dialog offers. +- **Login sessions (SHARK-3577)** — `mgmt_list_sessions` (`GET +/auth/session/ui/all`, read-only), `mgmt_revoke_session` and + `mgmt_logout_other_sessions` (both `POST /auth/session/ui/delete`, both + HITL-gated). This is the incident-response surface, so four operational facts + matter here rather than only in the code. (1) **The route carries no client IP + and no last-seen time.** It has `created_at`, `expires_at`, `current_session` + and a five-field `creation_details` (os, os_version, browser, browser_version, + device), and nothing else. Support must not promise a customer an IP; the tool + states the absence on every listing. (2) **`POST /auth/session/ui/logout` is + deliberately NOT wrapped.** It is `logoutCurrentSession()` on the console's own + client, nothing in the console calls it, and its name says it ends the CURRENT + session — so "terminate all others" is done the way the console does it, + by deleting every handle except the current one. (3) **Self-revocation is + allowed**, with the consequence first on the consent page; the bulk logout + never does it, and refuses outright if the gateway marks no session as the + current one. (4) The session `token_key` is treated as **credential-grade and + never rendered anywhere** — sessions are addressed by a `session_ref` (`s-` + + eight hex of a per-process keyed digest), which means **refs do not survive a + restart**: after a redeploy a caller must re-run `mgmt_list_sessions` before + revoking, and a stale ref is refused rather than resolved. Unlike the Platform + API key trio these tools do **not** refuse under a team account, because a + session belongs to the login; the per-route evidence is in the same + `groupScope.ts`. Neither route is MFA-gated, so no code is asked for. + (5) **SHARK-3586 — that team-account sentence was false until the client said + it too.** Both routes were merely ABSENT from `GROUP_SUPPORTED_ROUTES`, which is + not opting out: `resolveGroup` defaults a call to the session's selection, so + under any selected team account all three session tools raised + `AccountScopeError` and the whole incident-response path refused. They now pass + `group: null` explicitly, and `test/mgmt-account-scope-completeness.test.ts` + asserts the class for **every** gateway method rather than for these two, so the + same omission cannot ride in on the next route. +- **Team management (SHARK-3554)** — thirteen tools over the gateway's + `GroupManagementEnabled` routes: `mgmt_get_team`, `mgmt_can_create_team`, + `mgmt_create_team`, `mgmt_rename_team`, `mgmt_invite_teammates`, + `mgmt_cancel_invitation`, `mgmt_resend_invitation`, + `mgmt_list_my_invitations`, `mgmt_accept_invitation`, + `mgmt_reject_invitation`, `mgmt_set_member_role`, `mgmt_remove_team_member` + and `mgmt_leave_team`. Five operational facts matter here rather than only in + the code. (1) **The family splits by SUBJECT, and the split is enforced at the + client.** Eight routes are about ONE TEAM and carry `?group=`; five are about + the LOGIN (`POST /auth/groups/new`, `GET /auth/groups/new/isAllowed`, `GET +/auth/invitations`, and the invite `accept` / `reject` pair) and pass + `group: null`, because they are on the gateway's plain `secureRouter` where a + `?group=` is silently dropped rather than rejected. Accept and reject take the + team in their **body**, resolved from the invitation record, so a caller with + team A selected who accepts an invitation from team B joins B. (2) + **`transfer_assets` on team creation is the most consequential argument on this + surface.** It moves EVERY asset off the personal account onto the new team and + the gateway then invalidates the access token, so the login is signed out. It + defaults to false, it cannot be reached without a human approval, and the + approval page leads with both consequences and with the account the assets + leave, by address. Support should expect a customer whose session dies right + after a team creation: that is the documented gateway behaviour, not a fault. + (3) **The batch invite reports per address.** A mixed reply is normal — the + gateway's own controller appends the addresses its validator rejected to + whatever the service returned — so never read one outcome for the whole call. + An empty results array is reported as unobserved, never as success. (4) + **The last OWNER is protected by this shim, not by the gateway**, and that was + checked rather than assumed: `DELETE /auth/groups/leave` carries an empty role + list in the gateway's acl map (which the middleware reads as "any member"), and + all three member-mutating controllers hand the decision to a gRPC service that + is not part of the accounting gateway. Demoting, removing or leaving as the + team's only owner is refused before an approval is minted, because a team with + no owner cannot be managed by anyone and no route here or in the console + appoints one. An OWNER or ADMIN is separately refused `mgmt_leave_team` by the + console's `permissionsMap`, which gives `TeamLeaving` to DEV and FINANCE only. + (5) **Email addresses are personal data and are handled by rule.** Never + logged; masked in a member listing and in every `_meta`; shown whole only in a + pending-invitation listing (where `{email}` is the sole handle the cancel and + resend routes accept) and on an approval page (where a human has to be able to + check who is affected). + +### Confirmation is the shim's gate; MFA is the gateway's (SHARK-3381, adjusted per SHARK-3392) + +**ACCEPTED RISK, recorded 2026-08-06 (Mike's call): the payment initiators carry +no second factor and will not get one.** `mgmt_deposit_with_card` and +`mgmt_subscribe_recurrent` move no money. Each creates a Stripe **hosted Checkout +session** and returns the checkout URL; nobody is charged until a human opens it +in a browser and completes Stripe's own form, with the card details and whatever +step-up the issuer requires. The agent never sees card data and cannot complete a +payment by any sequence of tool calls, so the worst outcome available to a +prompt-injected agent on these two tools is producing a link, and even that is +behind the HITL gate below, which needs a fresh interactive login the agent cannot +perform. A TOTP on top would gate the making of a URL rather than the money, would +lock out every account that has not enrolled 2FA (the gateway lets those through +by design), and would put a live second factor into an agent transcript. It is +refused on product and on security grounds, not deferred. +SHARK-3392's OTHER half, the `/confirm` self-approval path, was NOT declined: it +shipped, and it is the fresh-login approval described immediately below. + +- **`confirm: true` is a UX affordance, NOT a security boundary.** It is a + model-set input the agent can forge, so it can never be the gate on its own; a + dry-run preview is a convenience, not a control. +- **Human-in-the-loop (HITL) is the shim's only gate, required for destructive + actions.** Every destructive/irreversible or alert-suppressing write requires + an out-of-band human confirmation the model cannot fabricate: a short-lived, + single-use **confirmation token** bound to `{action, sha256(args), sub}`. The + token is minted on the first tool call but is INVALID until a human approves + it. **Approval (SHARK-3381 option A) is a FRESH interactive UAuth login**, not + the agent's bearer: `GET /confirm/:token` starts a browser Google/UAuth login + (reusing the whitelisted `/callback`), and approval succeeds only when the + freshly-logged-in human's **stable account id (`unique_id`)** equals the + token's bound `sub`. After the login the shim does NOT approve as a side + effect: it renders a **consent page** describing the action in words (a + direction-bearing summary, the object affected, the concrete effects, an + explicit warning when it cannot be undone, the account as its ETH address, and + the absolute expiry of the link — everything HTML-escaped, no API key ever + rendered, and the raw argument dump kept only as a fallback). That last claim + is structural rather than incidental (SHARK-3513), and rests on **three + independent layers**, each of which is now separately pinned by + `test/mgmt-secret-masking.test.ts` (SHARK-3513 pass 5 — until then only the + third had a test, and deleting the first left the whole suite green): + (1) `argsPreview()` masks secret-NAMED values to their last 4 characters BEFORE + serialising, so the pending entry never holds a full key; (2) it then sweeps the + serialised string for anything key-SHAPED, catching a credential hiding under an + innocent argument name; (3) the fallback row is redacted again at render time, + because it can carry a preview string built elsewhere. So the claim holds even + for a gated tool that supplies no display payload. + Since SHARK-3522 the **same description is echoed back to the model** in the + needs-approval tool result, read out of the pending entry so the human-facing + page and the agent-facing transcript cannot state the action in different + terms; the account address is the one field kept for the human alone. It + requires a **deliberate POST `/confirm/approve`** carrying a one-time consent + ticket (rendered only to the authenticated browser — the anti-CSRF capability), + so a mere link click while logged in cannot grant approval. The agent's + shim-JWT `sub` is that same `unique_id`, so the human and the agent session + resolve to the SAME account — while a prompt-injected agent, holding no + interactive UAuth credential, cannot complete the login and therefore cannot + self-approve. (An MCP `elicitation` URL round-trip may surface the approval + link, but the approval itself is always the `/confirm` login + consent POST.) + The whole round-trip is **browser-bound**: a same-site, http-only cookie set at + `GET /confirm/:token` is re-checked at `/callback` and at `/confirm/approve`, so + a link opened/triggered in a different browser context cannot complete the + approval. The HITL gate is **not approvable on the headless `MGMT_LEGACY_TOKEN` + path** (no interactive login to match the bound sub) — it refuses up front with + a clear message (fails closed, the safe direction). +- **MFA (TOTP) is verified by the accounting-gateway; the code is COLLECTED on + the approval page.** The gateway is the MFA authority: its + `src/middleware/mfa.go` `AuthorizeAccess` middleware calls `VerifyTotp` on the + routes in its `targetList`. **SIX** of the routes this shim calls are gated + (SHARK-3584 read the list directly rather than inferring it from the console's + client; the count said "three" before that and **"five" until SHARK-3568** — + the sixth shipped with SHARK-3578 and this table did not follow it): + + | Gated route | Tool | + | --------------------------------------- | ------------------------------ | + | `DELETE /auth/jwt` | `mgmt_delete_api_key` | + | `PATCH /auth/whitelist` | `mgmt_edit_allowlist` | + | `POST /auth/payment/cancelSubscription` | `mgmt_cancel_subscription` | + | `POST /auth/token/custom/new` | `mgmt_create_platform_api_key` | + | `POST /auth/token/custom/delete` | `mgmt_delete_platform_api_key` | + | `POST /auth/abstractBindings/unbind` | `mgmt_unbind_login_method` | + + The in-shim list is `MFA_GATED_ACTIONS` in `src/mgmt/tools/twoFactor.ts` — ONE + table mirroring `targetList`, deliberately not a flag at each handler, because + a handler that forgets the flag simply stops asking for a code and nothing + fails loudly.

It is never handed to the model: not in the + needs-approval text, not in `_meta`, not in the rendered page. Before this, an + account with 2FA spent a real human approval and then got back a raw + `HTTP 400 {"error":{"code":"2fa_required"}}` it could not act on. + + The shim reads `GET /auth/2fa/status` to decide whether to ask, caching a + definite answer for 5 minutes (`mgmt_get_2fa_status` exposes the same read). + The cache EXPIRES rather than lasting the session on purpose: a user who hits + this wall, goes and enrols, and comes back must be asked for a code on their + next attempt, not hours later when the session ends. **An unreadable status means + POSSIBLY ON, never off**: the page asks and accepts an empty answer, so a + status outage cannot block an account that has no second factor. When the + gateway does refuse with `2fa_required` or `2fa_wrong`, the reply says so in + words and names the next step instead of surfacing the 400. + + **2FA management stays OUT** by Mike's decision (2026-08-01): `POST +/auth/2fa/init`, `/confirm` and `/clear` are not exposed, so this server can see + whether a second factor exists and can never enrol, change or remove one. + +- **Payment initiators (SHARK-3377)** — `mgmt_deposit_with_card` (`POST +/auth/payment/depositWithCard`) and `mgmt_subscribe_recurrent` (`POST +/auth/payment/subscribeOnRecurrentPayments`) are **HITL-gated writes** (see the + "Confirmation" section above; these routes are **not** MFA-gated at the + gateway) that start a **Stripe Checkout** session and return the **hosted + checkout URL** for a human to open and pay in a browser. The agent never sees + or handles card data and cannot charge autonomously; the returned URL is + **not** a secret. + Reads: `mgmt_get_subscriptions`, `mgmt_card_payment_eligibility`, + `mgmt_get_subscription_prices`, `mgmt_get_invoice_details` (Stripe + invoice/receipt URLs via `GET /auth/document/invoice/stripeDocuments`). +- **The transaction ledger, and the invoice chain (SHARK-3575)** — + `mgmt_list_transactions` (`GET /auth/transactionHistory`) is a **read** that + lists this account's billing transactions over a window, with the route's own + cursor paging. It exists because `mgmt_get_invoice_details` needs a `txId` and + **nothing else in the set could produce one**, so the invoice read shipped + unreachable. Each row states date, kind, amount and currency (the route has no + currency field: `amount_usd` vs `amount_ankr` IS the currency), plus the chain + and reason where it carries them, and ends with the tx id the invoice tool + takes. `from`/`to` are the route's only **required** parameters; the tool + defaults a 30-day window and always prints the window it sent, in ISO and in + raw milliseconds, so an empty page is diagnosable rather than looking like an + account with no history. **Known limit, in the tool text:** a card payment has + Stripe documents behind its id, a **crypto deposit has none** (that invoice is + generated by `GET /auth/document/invoice/cryptoDeposit`, which needs the + on-chain tx hash and a billing name, neither of which the ledger carries, and + which this server does not wrap). With both URLs absent, + `mgmt_get_invoice_details` says which situations produce that instead of + printing two blanks. **`txType` is OPTIONAL, and that is what closes the chain + (SHARK-3575 follow-up):** the invoice route selects a document by + `DEPOSIT` or `BUNDLE`, the ledger's own `kind` enum contains neither value (it + is `proto.TransactionType`, and a bundle purchase arrives as a `DEDUCTION`), and + nothing documents a mapping between the two, so a row cannot say which type + holds its document. Omitted, the tool asks for `DEPOSIT` and then for `BUNDLE` + only if the first answered with no document, and names the type that held it in + `_meta.tx_type`. Two read-only GETs at worst, and only on a miss. +- **Stopping a recurring payment (SHARK-3546)** — `mgmt_cancel_subscription` + (`POST /auth/payment/cancelSubscription`) is a **HITL-gated destructive write** + and the one payment route that IS **MFA-gated** at the gateway, so a code is + genuinely forwarded and verified there (and, since SHARK-3584, collected on the + approval page when the account has 2FA). It exists because the + subscribe tool's own approval page promises the charge repeats "until it is + cancelled": a surface that can start a recurring charge and not stop it is the + defect. The approval page names the amount, currency and billing period being + stopped, the paid period that is **not** refunded, and what does **not** stop + (other subscriptions, pay-as-you-go usage). The route answers with an **empty + body**, so the reply reports the request as ACCEPTED and points at + `mgmt_get_subscriptions` instead of asserting Stripe's resulting state. +- **Per-project spend without a per-key approval (SHARK-3555)** — + `mgmt_get_spending_breakdown` (`GET /auth/stats/spendings/aggregated`) is a + plain read returning the per-chain AND per-project split in one unscoped call. + Its `per_projects` map is keyed by each project's **endpoint token, a live RPC + credential**, so the tool renders it **masked to the last 4 characters** and + keeps it out of `_meta` too. That mask is load-bearing rather than cosmetic: + rendering the map verbatim would hand over every key on the account from an + unapproved, read-only-annotated tool, which is the `mgmt_reveal_api_key` + approval gate defeated by reading a usage endpoint. +- **TOTP** — the destructive SHARK-3374 writes (`mgmt_delete_api_key`, key + freeze/create/edit, and every allowlist write: `mgmt_edit_allowlist`, + `mgmt_add_allowlist_item`, `mgmt_replace_allowlist`, `mgmt_set_allowlist_mode`, + `mgmt_set_blockchain_allowlist`) **and** the payment initiators accept an + **optional** `totp` arg, forwarded to the gateway as the `x-ankr-totp-token` + header and **never logged**. The two Platform API key writes (SHARK-3574: + `mgmt_create_platform_api_key`, `mgmt_delete_platform_api_key`) forward it too, + on the same evidence as the rest — the console's own client sends a TOTP header + on `POST /auth/token/custom/new` and `POST /auth/token/custom/delete`, and + sends none on `GET /auth/token/custom/all`, so the listing accepts no `totp` + rather than advertising a factor nothing checks. SHARK-3584 then **verified** + both of those against `mfa.go` instead of leaving them on the console's + evidence: both are `true` in its `targetList`. `mgmt_unbind_login_method` + (SHARK-3578) forwards one too, and its route is the sixth entry in that list. + The shim does **not** verify the TOTP — the gateway is the MFA authority and + verifies it on the six gated routes tabulated above.

Exits non-zero below the thresholds. **Read it as a floor, not as assurance:** it stood at 96.8% lines while five separately-verified security guards had no test at all — an executed line is not a checked line. **It is also intermittently red for a reason that is not about coverage:** this script does not set `COVERAGE_RUN=1`, so `counting bounds its own cost on a pathological payload` is held to its tight 500 ms budget while paying the V8 instrumentation cost, and it fails more often than it passes (390 / 506 / 534 / 570 ms over four runs). Check that test name before reading a red run as a regression; see README.md. | +| Coverage, WHOLE TREE (thresholds enforced) | `pnpm test:coverage` | everything outside `test/`, i.e. both planes | The merge of PR #25 split one script in two, and this row is the half that was missing. `pnpm test:coverage` fails below 90% lines / 80% branches / 85% functions, a HIGHER bar than the scoped gate above. A threshold triple quoted without naming its script is unfalsifiable now that there are two gates, so both are named here and `test/doc-gates.test.ts` checks each against the flags of the script it names. | +| Mutation (G5) | `pnpm mutation` | `src/**/*.ts` — BOTH planes | StrykerJS, config in `stryker.conf.json` — ONE file since the merge of PR #25, which arrived carrying a second Stryker config under a DIFFERENT filename; two configs that collide by meaning and not by path are merged without git ever raising a conflict, and Stryker then silently honours one of them. The names and the settings they disagreed on are recorded in that file's own `_comment`. This is the gate that catches an assertion that runs but checks nothing. Slow by construction (see below) — a nightly job, not a pre-commit hook. It is also not the way to measure one plane: read a whole-tree score per directory, never as one number, because the two planes have different test styles and a combined figure hides which half regressed. | +| Mutation, one file | `pnpm mutation:file 'src/mgmt/tools/confirmation.ts'` | ONE path per invocation, or one LINE RANGE (`…/confirmation.ts:370-373`) | Minutes, against hours for the whole-tree run. Scoping a run is this command's job, not the config glob's. The line-range form is how a specific guard is verified, and what a claim like "this guard is pinned" should cite. **Repeating `--mutate` does not add a second file, it replaces the first** — see below. | + +Why the mutation run is slow: the suite is Node's own test runner driven through +`tsx`, so Stryker has to use its `command` runner and cannot see which test +touched which line (`coverageAnalysis: "off"`). Every mutant therefore costs one +full suite run. Scope it. + +**`--mutate` is LAST-PATTERN-WINS: one file per invocation, always.** Stryker does +not union repeated `--mutate` flags. `stryker run --mutate A.ts --mutate B.ts` +silently measures **B alone** and reports a score for it as though both had been +covered. The tell is the log line `Found N of file(s) to be mutated` +(found in SHARK-3564): if that `N` is not what you asked for, the number you are +about to quote is not the number you think it is. Read `N`, not the total — the +total is just how many files the project has, it grows with every ticket, and it +is deliberately NOT quoted here: a number that moves whenever a file is added +goes stale silently, which is the failure this whole paragraph is about. The same applies to a +comma-separated list. So a per-file mutation gate is a LOOP of single-file invocations, and every +score quoted in a PR body names the one file it was measured on. + +Budget for it: a single file is minutes, not seconds. `groupScope.ts` took +**8m31s for 75 mutants** at the configured concurrency of 2 (re-measured at +SHARK-3568; it was 3m39s for 46 mutants when this paragraph was written, and the +file has grown since). Budget from the mutant count Stryker prints at the start +of YOUR run, not from a figure in this file: mutants scale with the file, so a +quoted duration ages out the moment anyone edits the code. The old whole-plane +figure that used to sit here (184 mutants, 15m08s) has been removed for the same +reason rather than updated, and the merge made it doubly wrong: `stryker.conf.json` +now mutates `src/**/*.ts`, so an unscoped `pnpm mutation` covers BOTH planes and +costs hours, not the quarter of an hour that figure described. It is a nightly +job and nobody should be planning around a stale number for it. The concurrency is +capped in `stryker.conf.json` for the +reason recorded there; raising it to make a run fit is how a laptop becomes +unusable, and it is not a threshold to lower either. A survivor is a missing test. + +What Stryker cannot express, and therefore has to be hand-checked: it has no +mutator that removes a function call or rewrites a numeric literal. So +`redactSecretsInPreview(...)` being dropped from the consent renderer, and +`app.set("trust proxy", num(env, 1))` becoming `true` / `0`, are verified by +editing the line, running the suite, and restoring it. Both are recorded in the +commit that pinned them. + +## Build & apply + +The mgmt image runs `dist/mgmt-http.js` on port `3100`. It is built from the +in-repo **`Dockerfile.mgmt`** — a clone of the data-plane `Dockerfile` that keeps +the same base-image digest and pnpm version and changes the port, the final `CMD` +(`["node", "--dns-result-order=ipv4first", "/app/dist/mgmt-http.js"]`) and one +thing more: it adds a `HEALTHCHECK` that hits `GET /healthz` with the built-in +`fetch`. **The data-plane `Dockerfile` carries no `HEALTHCHECK`** — both planes +serve `/healthz`, but only this image declares a container-level probe, so a +plain `docker run` of the data image reports no health. In Kubernetes this +changes nothing either way: the probes come from the Deployment, not the image. +Both Dockerfiles digest-pin the base image and drive pnpm from `package.json`'s +`packageManager` via corepack. + +**Where `GATEWAY_JWT_PRIVATE_KEY` comes from: Vault, and NOT from you.** It is not +an existing Ankr credential — it is an RS256 key belonging to this service alone, +which the shim uses to sign its own bearer tokens and nothing else uses. It +already exists and is STORED: the `ExternalSecret` in `infrastructure-k8s` reads +property `gateway-jwt-private-key` from the `vault-k8s-kv-store` ClusterSecretStore +at `aapi/mgmt-mcp-server`, on a 1h refresh, so the key survives a deploy and a +resync. **Do not generate one.** Minting a new key invalidates every live shim JWT +at once, which reads as an auth bug rather than as a rotation. + +**The deploy path, and there is no `kubectl apply` in it.** Images are built and +pushed by `build-and-push.yml` (with `--build-arg BUILD_COMMIT`, so the running +build is identifiable on the wire and on `mcp_ankr_build_info`). Everything else +lives in `w3tech/infrastructure-k8s` under +`argocd/apps/aapi/resources/agent-rpc-mcp/`, and ArgoCD applies it: the +per-cluster values, the Istio routing and that ExternalSecret. No manifest in THIS +repository describes the deployment. `DEPLOY-RUNBOOK.md` section 2 is the +operational entry point and `REVIEW-READY.md` 4b holds the full reading. + +**Secret hygiene.** `gateway_rsa_private.pem` (the RS256 shim signing key) must +never enter git or an image, and must never transit Slack or a laptop. `*.pem` is +git-ignored and the repo `.dockerignore` excludes `*.pem` / `*.key` / `*.crt` +(plus `.git`, `dist`, `test`, `deploy`, …), so a stray key in a build context +cannot be baked into a published image. + +### Host topology (mcp.ankr.com) + +The mgmt plane owns the **`mcp.ankr.com` root** — `/`, `/authorize`, `/callback`, +`/token`, `/register`, `/.well-known/*`, `/mcp`, `/healthz`, with +`MGMT_ISSUER=https://mcp.ankr.com`. The **data plane** is a sibling on the **same +host at the `/rpc` prefix**; the data app dual-mounts its handlers on both `/mcp` +and `/rpc`, so `/rpc` is routed straight through with **no rewrite**. + +That split is expressed in Istio, not in an Ingress: a `Gateway` +(`aapi-mcp-server-gateway`, HTTPS 443, TLS credential `mcp-ankr-com-tls` issued +by cert-manager) plus ONE `VirtualService` carrying both routes in written order — +first `uri.prefix: /rpc` to the data plane, then a catch-all to the management +plane. Both live in `infrastructure-k8s`. It must stay a single resource: Istio +merges VirtualServices bound to the same host and gateway, and the order of routes +contributed by separate resources is not guaranteed, so splitting them again would +let every `/rpc` request land on the management plane's 401 with both files still +looking correct. `DEPLOY-RUNBOOK.md` section 2 and `REVIEW-READY.md` 4b carry the +detail. + +## Auth: provider + UAuth application (Andrey's prod guidance) + +- **Provider = Google.** `UAUTH_PROVIDER_DEFAULT=AUTH_PROVIDER_GOOGLE`; the shim + drives the Google login flow (`getOauth2Params(provider=GOOGLE)` → + `loginUserByOauth2SecretCode`). +- **The shim token is issued to the MultiRPC UAuth app** (`UAUTH_APPLICATION=MultiRPC`), + **not** to a separate Management-MCP application and **not** with an `app=*` + wildcard. Per Andrey: the access token the shim obtains must be valid for + **MultiRPC backend queries** (the accounting-gateway resolves the account and + authorizes every `/auth/*` call from exactly this token), so it has to be a + MultiRPC-app token. ~~Registering the MCP as its own UAuth application~~ is + **no longer recommended** — that earlier guidance is withdrawn. + +## BLOCKED on auth team (prod) — must clear before go-live + +1. **✅ DONE — Whitelist the shim `/callback` Google redirect URL** (config only, + no backend change). **Denis Lozhkin confirmed (2026-07-01):** + `https://mcp.ankr.com/callback` is whitelisted as a **Google** redirect for the + **MultiRPC** app. **Topology:** the mgmt MCP owns the `mcp.ankr.com` root + (`/authorize`, `/callback`, `/token`, `/.well-known/*`, `/mcp`); the data-plane + RPC MCP is exposed at `mcp.ankr.com/rpc` (ingress path-prefix). This was + blocking `getOauth2Params` / `loginUserByOauth2SecretCode` — now cleared. + (The loopback / claude.ai redirect_uris the MCP **client** registers via DCR + are independent: they live in the shim's own clients store.) `getOauth2Params` + is verified (200 for `AUTH_PROVIDER_GOOGLE`, 400 for bare `google`), and a + full interactive login plus a human-approval round trip was completed on + 2026-08-06 with the consent page rendering, which is what settles that the + returned `accessToken` is accepted by the prod gateway and that both token + kinds carry the same `unique_id`. + + **The `ankrState` echo question is CLOSED, and the answer is the opposite of + what this section used to say (SHARK-3611).** It told the reader to confirm + UAuth echoes `ankrState` and then make the nonce check mandatory. UAuth never + echoes it: measured from the live 302, it folds our breadcrumb into the + provider's OAuth `state`, and the provider redirects to `/callback` directly, + so a real callback carries `code` and `state` and no `ankrState` at all. + Making the check mandatory would therefore have rejected EVERY login. The + check, the `MGMT_REQUIRE_ANKR_NONCE` variable and the `TODO(VERIFY prod)` are + removed; the one-time `state` round-trip is the guard and there is nothing + left to switch on. + +2. **Prod gateway config flags — CONFIRMED (values.yaml, per Andrey).** The + surface this PoC needs is live on prod: + + - `APP_ADDITIONAL_JWTS_ENABLED=true` — gates `/auth/jwt/additional` & + `/auth/jwt/*` (key CRUD). + - `APP_LOGIN_BY_TOKEN_V3=true` + abstract-auth/`oauth2` routes active — the + `LoginByTokenV3` UAuth handler (`uauthController.LoginUserByOauth2SecretCode`) + is the live one. + - `APP_MFA_ENABLED=true` — the gateway's MFA middleware is active. **The + gateway is the sole MFA authority**: its `mfa.go` `AuthorizeAccess` + middleware `VerifyTotp`s the routes in its `targetList` — among the routes + this PoC calls, the **six** tabulated in the MFA bullet above. The shim + does **not** verify the `totp`; it forwards one as `x-ankr-totp-token` (see + `src/mgmt/gateway/client.ts` `request()`), and a login without 2FA is let + through by the gateway (no mandatory-2FA requirement). The same flag also + registers `GET /auth/2fa/status`, which is why an unreadable status must be + treated as POSSIBLY ON rather than off. + (`getMySyntheticJwt` is also on the MFA subrouter and is not exposed by this + PoC at all. `client.ts` used to carry a `getSyntheticJwt()` with NO `totp` + parameter and no callers, so it could never have satisfied that route for an + enrolled account; SHARK-3585 removed it rather than completing it, on Mike's + call. The team analogue `GET /auth/group/jwt` is NOT MFA-gated and is the one + this PoC wraps.) + +3. **MUST VERIFY LIVE — do the one-time login token and the exchanged session + token carry the SAME `unique_id`?** (SHARK-3373 pass 4.) + + The HITL binding compares an account id derived on two different legs, from two + different tokens: + + - the **agent** session's `sub` comes from the token the shim ends up + **holding**, i.e. the **exchanged session token** + (`tokenHandler` -> `uauthAccountSub(session.uauthAccessToken)`, after + `finishClientLoginLeg` swapped the one-time token via + `exchangeSessionKey` -> gateway `POST /auth/session/ui/new`); + - the **human approver's** `sub` comes from the **one-time login token** of a + fresh interactive login (`finishApprovalLeg` -> + `uauthAccountSub(login.accessToken)`). **That leg never exchanges.** + + Nothing we own establishes that the two tokens carry the same `unique_id`. + The flow is only coherent if they do. **If they differ, login succeeds and + EVERY HITL-gated write becomes permanently unapprovable** — the failure is not + a crash, it is a silent dead end. + + This is now explicit and tested from both sides in + `test/mgmt-identity-divergence.test.ts` (a fixture serves deliberately + divergent ids and asserts the refusal is loud, names the derivation mismatch as + a server-side cause, and tells the human a retry will not help), and the server + logs a `console.warn` naming the hypothesis on every subject mismatch. But a + fixture cannot settle what prod UAuth actually returns. + + **How to check at go-live:** complete one real interactive login, then complete + one real approval round-trip on any gated tool (e.g. `mgmt_freeze_api_key`). + If the consent page renders, the ids agree. If you get the **"Not approved: + account mismatch"** page while demonstrably signed in as the right account, + they do NOT agree — check the `[mgmt] HITL approval REFUSED on a subject +mismatch` log line, and fix it by exchanging the token on the approval leg too + (or by deriving both subjects from the same token kind). Do not ship the HITL + gate to users until this is confirmed. + +## Other follow-ups (not auth-team blockers) + +- **RBAC / scope model** — both halves now SHIP. **Correction (SHARK-3568): this + entry told an operator the PoC ships no per-tool RBAC and that role-based + capability gating was still open. Both stopped being true at SHARK-3553 + (`src/mgmt/tools/rolePermissions.ts`), and the team MANAGEMENT surface it also + listed as open shipped at SHARK-3554 — it is documented in the Tools section + above, in this same file.** What an operator needs to know about the gate: + it is a PRE-FLIGHT MIRROR, not an authorization boundary. It holds one in-shim + copy of the console's `permissionsMap` (four roles: `OWNER`, `ADMIN`, `DEV`, + `FINANCE`), maps every registered tool to the capability it needs, and refuses + in `withAccountScope` BEFORE the handler runs and therefore before an approval + link is minted — so a human is never asked to log in and click for an action + the gateway will reject anyway. It costs no request (the role travels with the + account selection). Three consequences for triage: (1) **the gateway stays the + authority** — a call the mirror allows can still be refused there, and that + refusal reaches the caller in the gateway's own words, so a support report of + "denied" is not evidence about which layer denied it; (2) **it fails OPEN** on a + role the gateway did not report or one this shim does not model, deliberately, + so a fifth role appearing on the gateway does not break every + capability-bearing tool overnight; (3) **it never applies to a personal + account** — roles exist only for team accounts, a personal account has no + selection and therefore no role to reach, and nothing renders or implies a + missing one. Refusals name the account, the role, the missing capability and + the roles that carry it. Separately, **Correction (SHARK-3552):** this section + used to call `?group=
` an unverified guess + and told readers not to build on it. That was wrong, and it was a claim about our + own backend that nobody had checked. The console (`w3tech/web3api-frontend` @ + `fe773bd`) declares `IApiUserGroupParams { group?: Address }` and passes it to + nearly every accounting-gateway `/auth/*` call, i.e. to the routes on the + gateway's `groupSupportedRouter`. Account scope therefore SHIPS: the session + `AccountScope` is applied once in `request()` + (`src/mgmt/gateway/client.ts`), the verified route list is in + `src/mgmt/gateway/groupScope.ts`, and a route that is NOT on that list refuses + while a team account is in force rather than answering for the login's own + account. **SHARK-3587 re-grounded that list on the gateway and re-keyed it.** + The evidence is now `w3tech/multirpc-accounting-gateway` itself at `470f9a4` + (`src/route/router.go` plus `src/middleware/groupacl.go`) rather than the + console, and the key is METHOD plus PATH rather than PATH, because Go registers + handlers per method and path and the gateway's own group ACL keys its lookup as + `fmt.Sprintf("%s %s", r.Method, r.URL.Path)` (`groupacl.go:579`). Keyed on path + alone, a GET could inherit a sibling PATCH's evidence. +- **Account selection ships; the detection stays** (SHARK-3544, corrected by + SHARK-3552). One person can own several Ankr accounts, and which one a session + starts on is decided by the bearer it signed in with; a relogin can land on a + different one (observed live on 2026-07-29). This entry used to say there was + nothing to select WITH. There is: `mgmt_list_accounts` enumerates what the login + can act on (`GET /auth/group`), `mgmt_select_account` aims the session at one of + them, and every account-scoped call then carries `?group=` on the same bearer, so + acting on a team account no longer means signing in again. The DETECTION is + unchanged and still the safety net, in `src/mgmt/tools/accountScope.ts`: every + result that changes state, and every account-scoped read answer, ends with the + account it applied to, and a caller can assert it (`expectAccount` on any tool, + or `mgmt_pin_account` once at session start), which refuses and names both + addresses on a mismatch. It now measures against the account IN FORCE, so after + selecting a team account a call pinned to the personal one is refused before the + gateway is called. Operationally: the account in a tool result, in + `mgmt_whoami` and on the `/confirm` page is the same value, so a wrong-account + action is visible in the transcript alone. What is still refused rather than + guessed: an address the login holds no seat on, and an account list that cannot + be read. The "four reads whose routes the console never scopes" that used to be + listed here are gone: SHARK-3587 read the gateway and found all four registered + on `groupSupportedRouter`, so they scope like everything else (see row 6.3 of + `USER-STORIES.md`). What still refuses is the Platform API key trio, on + `secureMfaRouter` where a `?group=` would be silently ignored. +- **MFA is verified by the gateway, not the shim.** The shim's only gate is the + HITL confirmToken; `totp` is **optional** at the shim and is forwarded as + `x-ankr-totp-token`, never logged. A login without 2FA is let through by the + gateway (no mandatory-2FA requirement). The six gated routes are tabulated in + the MFA bullet above. + + The UX follow-up this used to record — "how does the human supply a fresh code + at call time, since codes are short-lived" — is **closed by SHARK-3584, and not + the way it was framed.** It said "the agent must prompt for it", which would + put a live second factor in a chat transcript and make the agent hold it. The + code is asked for on the **approval page** instead: the human is already there, + already at their authenticator, and the code travels with the approval into the + write without the model seeing it. A code is valid for about 30 seconds and the + page is the last step before the request, so the timing works out; a stale code + comes back as `2fa_wrong` and the reply says exactly that. + +- **Shared store before `replicas > 1`.** The session/PKCE store, the + shim-JWT→UAuth-token map, the rate-limit buckets, and the SHARK-3381 HITL + confirmation-token store are all per-pod in memory.

What has to change on the deployment side + +Updated 2026-08-06, after K8S-1107 closed most of this list. What that change +already did: pinned both planes to builds of this branch, bumped the data plane +to 256Mi, and synced both applications (data 12:43:56Z, mgmt 12:46:35Z, both +Healthy). Images were already pinned by git sha before it. + +Still open: + +1. **Pass `--build-arg BUILD_COMMIT` in the image build**, one line in + `build-and-push.yml` on the `deploy/*-helm` branches. Without it the served + version is a bare `0.2.0` even though the deployed build already carries + `src/buildInfo.ts`, so the sha lives only in the registry tag and cannot be + read from the wire. +2. **Bring the two planes to the same commit.** The data-plane image contains + this whole branch; the management-plane image was cut from `f71f30b` and does + not. Nothing in the newer commits changes shared runtime behaviour, so this is + currently benign, but the two are meant to roll together. +3. **Confirm `replicas: 1` and strategy `Recreate` on the management plane.** + Every store there is per process: MCP sessions, DCR clients, PKCE, HITL + confirmations, and the shim-token to UAuth-token map. More than one replica + breaks sessions, approvals and registered clients, and sticky routing fixes + only the first. +4. **Route timeout on the Istio VirtualServices.** `GET /rpc` and `GET /mcp` are + long-lived SSE streams. A default timeout cuts them mid-stream, and the symptom + is an agent that goes quiet rather than an error. +5. **`X-Forwarded-For` reaching the pod**, matching `TRUST_PROXY_HOPS=1`. +6. **Decide where edge rate limiting lives.** There is none today on either + plane, and no CDN in front of `mcp.ankr.com`. The in-process bucket on the + control plane and the 20-message batch cap on the data plane are the only + bounds that exist. +7. **Confirm the mgmt ExternalSecret holds a fixed `gateway-jwt-private-key`.** + If it is regenerated on a resync, every live session dies at once and it looks + like an auth bug. + +Two readings still outstanding, both bearing on items 3 and 6: + +```sh +kubectl -n agent-rpc-mcp get deploy agent-rpc-mgmt-mcp \ + -o jsonpath='{.spec.replicas}{" "}{.status.readyReplicas}{"\n"}' + +kubectl -n agent-rpc-mcp get destinationrule -o yaml | grep -A5 consistentHash +``` + +## 6. Rollback + +State the target BEFORE deploying, because nothing on the wire or in the registry +currently distinguishes builds. Capture the running digests first: + +```sh +kubectl -n agent-rpc-mcp get pods -l app=agent-rpc-mcp \ + -o jsonpath='{range .items[*]}{.status.containerStatuses[0].imageID}{"\n"}{end}' +kubectl -n agent-rpc-mcp get pods -l app=agent-rpc-mgmt-mcp \ + -o jsonpath='{range .items[*]}{.status.containerStatuses[0].imageID}{"\n"}{end}' +``` + +Rollback is pointing the ArgoCD applications back at those digests. + +Know what any roll costs, in either direction: + +- **Data plane:** every live MCP session is dropped. State is in process memory + and the strategy is `Recreate`. +- **Control plane:** the same, plus **every registered OAuth client is + invalidated**, and the next call fails `invalid_client: Unknown client_id` + until the client registers again (SHARK-3547). Tell anyone using it before you + roll. + +This is an accepted allowance for the current stage, with a stated expiry: +externalise the state before this is announced as generally available, or before +either plane carries traffic that makes a deploy-time drop visible to a customer, +whichever comes first (REVIEW-READY.md section 4.2). + +## 7. Traps already paid for + +- **A blank allowlist blocks the deploy, deliberately.** `MCP_ALLOWED_HOSTS=" "` + throws at construction, so the pod fails readiness, Kubernetes does not + complete the rollout, and the previous pod keeps serving. That is the better + failure: the alternative was a stray space silently disabling DNS-rebinding + protection on a public ingress. +- **Observability shipped in SHARK-3607, and the remaining gap is the ALERT.** + Both planes serve `mcp_ankr_*` metrics and structured logs (section 9). What is + still missing is an alert on the ABSENCE of the scrape: SHARK-3608 carries + `McpNoScrapeTarget` = `absent(up{namespace="agent-rpc-mcp"})` for 10m, unmerged + in `infrastructure-observability` #310. That gap is not theoretical — the chart + merge dropped the Service labels a `VMServiceScrape` selects on, and neither + plane was scraped for hours while the pods stayed Healthy, ArgoCD stayed green + and traffic kept flowing. Nothing paged, because nothing alerts on silence. +- **The `Recreate` gap is still real, even though the drain signal now exists.** + `/healthz` (liveness) and `/readyz` (readiness) are separate since SHARK-3607, + so a deliberate drain is distinguishable from an incident — but the Deployment + is `replicas: 1` with `strategy: Recreate`, so every roll still has a window + with no pod at all. What the split buys is telling the two apart, not closing + the window. + +## 8. The served surface + +The same handlers are **dual-mounted on `/mcp` and `/rpc`**, so no rewrite is +needed at the edge. `/mcp` is the back-compat path; `/rpc` is what is actually +routed, because the management plane owns `mcp.ankr.com/mcp` (section 2). + +- `POST /mcp`, `POST /rpc` — MCP requests. `initialize` creates a session; the + `Mcp-Session-Id` header is reused after. +- `GET /mcp`, `GET /rpc` — server-to-client SSE stream for an existing session. +- `DELETE /mcp`, `DELETE /rpc` — session teardown. +- `GET /healthz` — liveness, `{ ok: true }`, unconditional. +- `GET /readyz` — readiness, `{ ready, draining }`; `200` while serving and `503` + from the moment a drain starts. +- `GET /metrics` — Prometheus exposition on a **separate listener** + (`METRICS_PORT`, default `9464`), never on the public port and never routed. + +**Auth on the data plane**: every request carries the caller's own Ankr key +(`x-ankr-api-key` or `Authorization: Bearer `), passed straight through to +`rpc.ankr.com`; no key gets a `401`. There is deliberately **no in-app rate +limiting and no keyless trial** — quota and per-key limits belong to Shark and +the edge, and duplicating them here would only cap a paying key below its plan. + +**Two bounds that are constants, not variables.** Request bodies are capped at +4mb on `/mcp` and `/rpc`, answered as a JSON-RPC error (`413` / `400`) rather +than an HTML error page. A JSON-RPC **batch** is capped at 20 messages +(`MAX_JSONRPC_BATCH` in `src/bodyLimit.ts`) and a larger one is refused `413` / +`-32600` before any of it runs. The batch cap is the one that matters for load: +the transport executes every entry concurrently, so at 4mb a single request could +drive roughly 25,000 upstream calls, and the edge limits REQUESTS, not calls. On +this plane `initialize` accepts any non-empty key string, so that fan-out is +reachable pre-auth. + +**Trust proxy is a HOP COUNT, never `true`.** `true` makes express derive +`req.ip` from the left-most `X-Forwarded-For` entry, which is client-controlled: +an attacker rotating the header mints a fresh rate-limit bucket per request. Set +`TRUST_PROXY_HOPS` to the number of proxies in front of the app (1 for a single +hop) and have the edge append the real client IP. + +## 9. Observability (SHARK-3607) + +### Metrics + +Every metric is named `mcp_ankr_*` and carries a `plane` label (`data` / `mgmt`). +**The prefix is a deployment constraint, not a style choice**: vmagent in +`do-fra1-03` applies a `keep_metrics` relabel with an explicit prefix allowlist, +so a name outside it is dropped silently between the pod and central +VictoriaMetrics — `/metrics` looks perfect and the dashboard stays empty. +`mcp_tool_calls_total` is already taken by the internal `shark-agent/mcp-server` +gateway, which is why the second segment exists. + +| Metric | Answers | +| -------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------- | +| `mcp_ankr_http_requests_total`, `..._http_request_duration_seconds` | availability, error rate, latency, per normalised route | +| `mcp_ankr_jsonrpc_requests_total` | which MCP methods are actually used | +| `mcp_ankr_tool_calls_total`, `..._tool_call_duration_seconds` | per-tool volume, failure and latency | +| `mcp_ankr_upstream_requests_total`, `..._upstream_duration_seconds` | is it us or `rpc.ankr.com` / AAPI / the gateway / UAuth | +| `mcp_ankr_sessions_live`, `..._session_limit`, `..._sessions_created_total`, `..._sessions_closed_total` | headroom against the cap, and how sessions end | +| **`mcp_ankr_refusals_total`** | **every deliberate bound this service enforces**, by `control` | +| `mcp_ankr_dcr_*`, `mcp_ankr_oauth_leg_total`, `mcp_ankr_confirmations_total` | management plane: registry occupancy, OAuth funnel, human-approval gate | +| `mcp_ankr_unhandled_faults_total` | faults the last-resort handlers absorbed (the process is up but sick) | +| `mcp_ankr_build_info` | which build is serving, so a deploy is visible on the board | + +`mcp_ankr_refusals_total` is the one to look at first during an incident.

"Which customer" +is answered by `key_ref` in the logs, never by a label. + +### Logs + +One JSON object per line on stderr.

What the review round closed + +Nine findings survived adversarial verification: four high, three medium, two +low. All nine are fixed. Each one below names the evidence. + +### High + +**1. `rpcCall` admitted 21 methods that change state, two of which broadcast.** +`src/tools/rpcCall.ts`. The read allowlist is substring-based, and the `fee` +token admitted `bumpfee` and `psbtbumpfee`, Bitcoin Core wallet RPCs that create +and broadcast a replacement transaction. Verified against the running data plane: +an MCP session opened with the key string `x` had `bumpfee` forwarded upstream, +while `sendrawtransaction` was refused locally with `METHOD_NOT_ALLOWED`. The +`block`, `chain` and `scan` tokens admitted bitcoind's chain-tip and storage +controls (`invalidateblock`, `pruneblockchain`, `rescanblockchain` and others), +and `block` and `trace` admitted the non-read half of geth's `debug_` namespace, +including the calls that write a file on the node. The module header calls itself +"THE PRIMARY AND ONLY BROADCAST/SIGNING CHOKEPOINT" and the shipped tool +description promised these were refused "with no exceptions", so the description +was wrong in the direction that matters. + +Fixed structurally where possible rather than by growing a denylist: `fee` is no +longer a read token (the four genuine fee reads are exact entries, so the whole +`bumpfee` family falls to default-deny), `debug_` is default-deny with a read +prefix list (listing the mutators goes stale on every geth release, listing the +reads does not), and there is a setter rule plus an exact set for the bitcoind +controls whose tokens real reads depend on. Evidence: a corpus of 71 real mutator +names and 93 real read names, run through `isPermittedMethod` before and after. +21 mutators were admitted before, 0 after. No read changed status: the one name +the corpus reports as refused, `debug_preimage`, was already refused before this +change and matches no read token. The description is executed against the guard by +the existing truthfulness tests, and the 21 names are a regression test. + +**2. One unauthenticated request could fan out to thousands of upstream calls.** +`src/bodyLimit.ts`, mounted on both planes. The MCP transport executes every entry +of a JSON-RPC array, and the only bound was the 4mb body limit. Measured: a 327 KB +body carrying 2000 `tools/call` entries returned 2000 responses in one 200 OK in +0.53 s, so 4mb allows roughly 25,000 invocations per request; and the entries run +concurrently, not in series (a batch of 1 took 0.45 s, a batch of 40 took 1.87 s, +not 18 s). On the data plane `initialize` accepts any non-empty key string, so all +of it is pre-auth. Now capped at 20 messages per request, refused with 413 and +`-32600` before the transport sees the body. + +**Correction (2026-08-06), and it makes this finding worse rather than better.** +This paragraph used to claim a draft Ingress in this repository bounded requests +at `limit-rps 20` even though it did not bound calls, which read as "there was +already one limit and this adds the second". There is no such limit in +production: that is an ingress-nginx annotation, production runs Istio, and the +Ingress it sat on was never applied to any cluster. Those drafts were deleted on +2026-08-07 for exactly this reason. So the batch cap added here is not the second +bound on this path, it is the only one. Evidence: 7 new tests, the load-bearing ones counting +upstream calls at `globalThis.fetch` (a refused batch performs zero); unmounting +the guard turns 4 of them red. + +**3. Unauthenticated DCR registrations evicted other people's OAuth clients.** +`src/mgmt/auth/session-store.ts`. `POST /register` is unauthenticated behind only +the in-app per-IP bucket, and `registerClient` did FIFO eviction of the oldest +client at capacity, so a flood of entirely valid registrations invalidated the +clients that had registered first. Reproduced end to end with +`MGMT_MAX_DCR_CLIENTS=2`: the victim's next `GET /authorize` answered +`400 invalid_client`. Now it applies the rule the session registry already states +in its own header, which is that at the cap a new entry is refused and no live +entry is ever evicted, with a 503 and `Retry-After: 60`. A per-source cap was +added as well, because refusing alone would still let one source fill the map and +lock everyone else out, and a TTL reclaim now runs before either bound fires so a +full registry recovers on its own. Evidence: 5 new tests including the finding's +own reproduction driven through the real app; restoring the eviction by hand turns +4 of the 5 red. + +**4. `buildProvider`'s wiring to `guardProvider` was untested.** `src/provider.ts`. +Demonstrated: replacing `return guardProvider(new AnkrProvider(url))` with +`return new AnkrProvider(url)` left 1521 of 1521 tests passing, typecheck clean +and lint clean. `guardProvider` is the only place the AAPI error sanitizer and the +30 second AAPI deadline are applied, and every AAPI tool takes its provider from +`buildProvider`, so that mutant puts the incident string "Method disabled, reason: +restricted by blockchain schema" back into agent-visible text, makes an +`AxiosError` whose enumerable `config.url` carries the caller's key eligible to be +inspected into a log line, and removes the only deadline on a stuck AAPI upstream. +The reason nothing noticed is that the only boundary test called `guardProvider` +directly on an object literal, and every test that goes through `createServer()` +stubs `AnkrProvider.prototype` with a resolving function, so no test ever drove a +rejecting AAPI call through the real `buildProvider`. One test now does, and it +kills that mutant. + +### Medium + +**5. `mgmt_list_toolsets` justified its token figures with two false claims.** +The comment said chars/4 was "the same estimator as `_meta.token_count` everywhere +else in this repo" and that it ran "about 25% high". Neither is true of the merged +tree: `_meta.token_count` is a real `o200k_base` count via `gpt-tokenizer` since +PR #25, whose own header records that SHARK-3525 removed chars/4 because it +understates usage, and chars/4 now appears exactly once in `src/`. Measured over +all eight selections, the estimate is 5.6% to 10.7% high, not 25%. The estimator +stays (see the tradeoff in section 4), both comments are corrected, `DEPLOY-MGMT.md` +now explains why it quotes the real counts while the tool prints estimates, and a +test computes the real number beside the estimate on every run and fails past 15%. + +**6. `installLastResortHandlers()` was never proved to be called by the shipped +entrypoint.** Demonstrated: deleting the call from `main()` left 1521 of 1521 +passing. The elaborate three-part test for it (a spawned child, a survival +assertion and a control proving the faults are fatal without the handlers) ran a +fixture that called the function itself and built its own listener, so it proved +the function works and proved it matters, and pinned neither that the entrypoint +calls it nor that it is called before the app is built. `main()` is now +`startServer()`, exported, and the fixture spawns that; the control swallows the +two registrations by patching `process.on` rather than skipping the call, so both +directions exercise the shipped path. Two more tests pin the order, using the fact +that `createHttpApp()` throws on a blank allowlist: with the handlers installed +first that boot fault is survivable, without them the process dies. Deleting the +call now fails a test, and so does moving it below `createHttpApp()`. + +**7. The `narrowable: true` flag on the fetch deadline had no test.** +Demonstrated: setting it to `false` left 1521 of 1521 passing. `getLogs`' +narrowing decision is pinned exhaustively for JSON-RPC body codes, but every one +of those stubs resolves with a `Response`, so the transport-failure path this +merge added to `src/net.ts` was never exercised. Two tests now reject at the +transport level: an all-failing stub gives widths `[4,16,8,4,2,1]` (with the flag +regressed it stops at `[4,16]`, and the call count pins that the halving +terminates instead of firing more requests at an overloaded upstream), and a +fail-once stub gives `[4,16,8,8]` with no `upstream_error` at all, which is the +case the flag exists for. + +### Low + +**8. `searchChain`'s `query` hint contradicted its own description.** The hint +offered "ENS name" as an accepted input while the description says ENS is not +resolved. The hint is what many MCP clients surface, so an agent spent a call and +got `kind:"ens"` back. Both now say the same thing, and a test reads the served +schema, checks it against the served description, and executes an ENS query. + +**9. `twoFactor.ts` named five MFA-gated routes; there are six.** +`MFA_GATED_ACTIONS` has held six since SHARK-3578 added `unbind_login_method`, and +the shipped instructions already said "Six gateway routes". The file's own +argument is that the gated set must live in one place because a missed entry fails +silently, so a header that undercounts is that same defect in prose: an auditor +reconciling it against `mfa.go` checks five of six. Corrected in three files, and +a test now parses the spelled-out number out of both the instructions and the +header and compares them against the set's real size. + +--- + +## 3b. Landed after the review round + +Four commits followed the adversarial review, all signed. They are called out +separately because they were NOT covered by that review's findings, and one of +them is a deliberate design reversal rather than a fix. + +**SHARK-3596 — the management plane silently dropped unknown arguments.** All 76 +management tools declared `inputSchema` as a raw shape, which the SDK wraps in a +plain `z.object` that STRIPS unknown keys. A misremembered argument therefore did +not fail; it produced a different, successful call. Measured on the deployed +build, `getAccountBalance({address, chain})` returned balances for every chain, +because `chain` is not a parameter there. On a plane that reaches API keys, team +membership and billing, that is the worst failure mode available: it succeeds and +it looks right. All 76 are now `z.object(...).strict()`, pinned by a behavioural +test that calls every tool with a bogus argument and asserts the key is named +back. The advertised schema cannot prove this on its own, since a stripping +schema and a strict one serialise identically. + +Two parts of that conversion could not be mechanical. `accountScope.ts` wraps +EVERY account-scoped tool and added its `expectAccount` argument by SPREADING the +schema; spreading a ZodObject copies internal fields rather than the schema, so a +blind conversion would have handed the SDK something unreadable on all of those +tools at once, without an error. It now uses `.extend()`. And `getTokenPrice` +named its chain argument `blockchain` while eleven of the twelve other +chain-taking tools say `chain`; it now advertises `chain` and keeps `blockchain` +as a DECLARED deprecated alias, because `.strict()` refuses an undeclared key and +shipping the strictness half alone would have broken every existing caller. + +**SHARK-3393 / SHARK-3560 — the `rpcCall` guard was reversed.** See section 4.5. + +**SHARK-3588 — session-store paths no test reached.** The sweep that bounds a Map +fed by an unauthenticated OAuth round-trip had no test at all; the error that +tells a caller WHICH registration bound was hit had its scope unasserted; and the +env parser that reads three deployment knobs had every guard survive. Seven tests +added, and `createSessionStore` gained an injectable clock so the `>` versus `>=` +expiry boundary is assertable at all. + +One of those tests was then found to be **green for the wrong reason**, by the +re-run of the mutation gate that was supposed to confirm it. Both sweep tests +read back through `retrieve()`, which enforces expiry INDEPENDENTLY of the sweep, +so they answered `undefined` whether or not `cleanup()` had removed anything. +This is the same defect class this branch keeps closing, committed in the test +itself. The reads now rewind the injected clock into the live window first, which +is the only way to tell a swept map from an unswept one through this API. It is +recorded in the file header, because the failure mode is silent: moving those +reads back to the expired instant makes the assertions vacuous without making +them red. + +## 4. Conscious tradeoffs and known limitations + +These are decisions, with their reasoning. None of them is an oversight, and each +is a thing a reviewer could reasonably want changed. + +### 4.1 A blank allowlist fails closed, and does not fall back + +`MCP_ALLOWED_HOSTS=" "` and `MCP_ALLOWED_ORIGINS=""` throw `AllowlistConfigError` +at construction on both planes. They do not fall back to the built-in default. + +The hole both sides agreed on is that an empty array is exactly how the MCP +transport spells "do not check", so a stray space in a manifest used to disable +DNS-rebinding protection on a public ingress while the protection flag stayed +switched on in the source. The two branches disagreed only on the remedy: the +management branch returned `undefined` and fell back to the built-in default, PR +#25 refused to serve. + +**This reverses an earlier call made during the merge.** The first pass chose the +fallback, on the grounds that the data plane's built-in default is the production +value (`mcp.ankr.com`), so falling back is both safe and available, whereas +refusing turns a typo into an outage of a public revenue-serving endpoint. That +was decided on a wrong picture of when the refusal happens. The throw is at +CONSTRUCTION, before a listener exists: the pod fails its readiness probe, +Kubernetes does not complete the rollout, and the previous pod keeps serving. So +the real choice is between a blocked deploy and a silently disabled security +control, and a blocked deploy is the better failure. Falling back also invents an +intent nobody expressed. + +The test that pinned the old remedy was not deleted. It was rewritten to assert +the same PURPOSE, which is that a blank value must never become allow-all, +against the chosen remedy. And the ordering tests added in this round make the +outcome observable end to end: the process stays up, does not listen, and logs +the fault, which is exactly what makes readiness fail rather than traffic drop. + +### 4.2 In-memory state on one replica is an accepted allowance, not an oversight + +Both planes hold their state in process memory: the MCP session registry, the DCR +client registry, the HITL confirmation store, and the map from shim token to UAuth +access token. Both charts pin `replicas: 1`, the management one also uses the +`Recreate` strategy, and production runs exactly one pod per plane, confirmed on +`up{job=~"agent-rpc-.*mcp"}` and by the SRE reading `kubectl` directly. + +**This is a deliberate allowance for the current stage of the product, made with +its costs known.** They are worth stating plainly rather than leaving a reader to +infer them: + +- every deploy of either plane is a short outage of that plane, because `Recreate` + stops the pod before it starts the new one; +- every deploy drops all live MCP sessions, all pending HITL approvals, and every + registered OAuth client, so a client that registered through DCR has to register + again (SHARK-3547); +- any single pod loss has the same effect as a deploy; +- there is no PodDisruptionBudget, no autoscaler and no second replica to fail + over to, so a node drain is an outage too. + +The allowance is defensible while the surface is early-access and the traffic is +small, and it is cheaper than building a shared store for a product whose shape is +still moving. It stops being defensible at a stated point, and that point should +be agreed rather than discovered: **externalise the state before this is announced +as generally available, or before either plane carries traffic that makes a +deploy-time drop visible to a customer, whichever comes first.** Until then, +scaling either Deployment past one replica silently breaks sessions, approvals and +registered clients, and sticky sessions only fix the first of those, so the +replica count is a control that must not be touched without that work. + +The bounds added in this round are written to that allowance. They are correct +per process, which is what protects a single replica's memory and event loop; they +are not a distributed rate limiter and they do not claim to be. + +### 4.3 The token catalogue keeps an estimator instead of the real tokenizer + +`mgmt_list_toolsets` reports chars/4 rather than a real `o200k_base` count. +Measuring it properly would import `gpt-tokenizer` into the management binary, +which `src/torpc/tokens.ts` measures at RSS 42 MB going to 111 MB steady, against +a 512Mi pod, for one advisory number in one tool. So the estimate stays and the +claim about it is now measured and gated instead of remembered. + +The visible consequence: `DEPLOY-MGMT.md` quotes the real counts (about 2.0k +tokens for `core`, about 27.4k for all 76) because that is what the test prints, +while the tool a user calls prints about 2.2k and about 29.8k. Two numbers for the +same quantity. Both are now stated as such, in both places, with the reason. + +### 4.4 The batch cap is a constant, and 20 is a judgement call + +`MAX_JSONRPC_BATCH = 20` is not configurable. A limit that can be widened by a +manifest edit is a limit that will be, and the rest of the posture is deliberately +resolved once at construction. 20 is an order of magnitude above anything observed +from real MCP clients, which send one message per request, but it is a judgement +call and a client that legitimately batches more would see a 413. If that ever +happens, the fix is a considered new number here, not an environment variable. + +### 4.5 `rpcCall` stopped deciding which reads exist, and that is a behaviour change + +The guard used to be a default-deny READ ALLOWLIST in front of the write rules. +It is now a write denylist only, and everything it does not refuse is FORWARDED +to the endpoint. This was a deliberate reversal, and it is the largest behaviour +change on the branch, so it deserves the reviewer's attention rather than a +footnote. + +Why it changed. The read half was the wrong layer and it failed in both +directions at once. Outward: `bumpfee` and `psbtbumpfee` create AND broadcast a +replacement transaction, and they cleared the allowlist on a `fee` token. Inward: +SHARK-3560 exists only because the allowlist refused ten legitimate EVM reads +that Ankr serves. Every chain onboarded made both directions worse, and each +round of patching it was the whack-a-mole SHARK-3393 named. + +Which reads exist is decided by two layers that are current by construction and +that a list in this repo can never match: the per-chain blockchain schema in the +proxy, which answers `-32075 Method disabled, restricted by blockchain schema`, +and the tenant the caller's authenticated session resolves to. What stays in the +code is the class neither covers, because the proxy FORWARDS broadcasts: +transaction broadcast and signing, transaction construction, node administration, +named node and wallet state mutation, mutating verbs, and the operational half of +geth's `debug_` namespace. + +Removed: 109 string literals of read surface; the file went from 522 lines to 437, and is 451 today after the SHARK-3599 description work landed on top. SHARK-3560 is dissolved rather than fixed, and the test that pinned its +refusals now pins the forwarding instead. + +THE RISK, stated plainly. A method no write rule recognises now reaches the +endpoint where it used to be refused locally. That is the intended trade: a +refusal from the schema is correct and current, a local refusal was neither. It +does mean the in-code guard is a narrower net than before, and the argument that +it is still the right net rests on the schema and the tenant actually holding. +Note the header of `src/tools/rpcCall.ts`: Shark's `tx_broadcasting` routing +profile FORWARDS broadcasts, so for the WRITE class this guard remains the only +chokepoint, and nothing about this change touches it. + +One regression was measured and closed during the change, which is the reason +this was verified by execution rather than by review. Running the known-mutator +corpus through the new guard surfaced five `debug_` calls that the allowlist had +been holding only as a side effect: `chaindbCompact`, `blockProfile`, `goTrace` +and two `standardTrace...ToFile`. Their mutating word sits mid-camelCase rather +than at a namespace boundary, so the verb rule did not reach them. After the fix +the corpus runs clean in both directions: zero mutators admitted, zero reads +broken, including all ten from SHARK-3560. + +### 4.6 SHARK-3593: user story 4.5 fails in production, for reasons outside this branch + +Row 4.5 of `USER-STORIES.md` (read invoices) is implemented and tested here, and +it fails in production on at least one account because the accounting gateway +answers 504 for that account's transaction history. That is a gateway problem, not +a shim problem, and nothing in this branch can fix it. It is tracked as SHARK-3593 +and should not be read as a defect in this code. + +### 4.7 SHARK-3547: the OAuth client registry still does not survive a redeploy + +The DCR registry is in-process. Every redeploy invalidates every registered +client, and the next call fails `invalid_client: Unknown client_id` until the +client re-registers. Row 6.4 of `USER-STORIES.md` is marked PARTIAL for this +reason. + +Finding 3 above is closely related but is not the same thing: it removed the path +by which a stranger could inflict that failure on you at will. The redeploy path +is untouched and needs the same shared store as 4.2. + +### 4.8 SHARK-3592: the control-plane limiter DOES limit, and the ticket is closed + +**Rewritten 2026-08-07. The heading used to read "the control-plane limiter's +production behaviour is unexplained", and the observability shipped in SHARK-3607 +explained it.** The limiter refuses in production, and the counter that says so +is now a metric anyone can read: + +``` +mcp_ankr_refusals_total{job="agent-rpc-mgmt-mcp", reason="bucket_empty"} +``` + +It stood at 150 on 2026-08-07. SHARK-3592 is closed in Jira. What made the +original observation ("250 requests in 2s, zero 429") look like a broken limiter +was that nothing in the process could be asked whether the bucket had ever +emptied, so the only evidence was the absence of a status code at the client. + +The competing explanation is also ruled out now. It required the requests to have +been spread over several independent buckets, which required several replicas. +There is exactly one pod per plane: `up{job="agent-rpc-mgmt-mcp"}` returns one +series, and so does the data plane's. One process, one bucket. + +One thing stays settled and is worth keeping so nobody repeats it: **the +`TRUST_PROXY_HOPS` fix applied on 2026-08-04 was a no-op.** The code already +defaults to 1 (`app.set("trust proxy", intEnv(process.env.TRUST_PROXY_HOPS, 1))` +on both planes), so setting the variable to 1 changed nothing. The per-cluster +values in `infrastructure-k8s` now set it explicitly to `"1"` anyway, which +documents the intent even though it does not change behaviour. + +What is NOT closed is the layer question, and it is a decision rather than a +finding. Neither Ingress in this repository is applied to the cluster; +production routes through Istio, which does not read ingress-nginx annotations +(section 4b). So the data plane's `limit-rps: 20` is not in force either, and +there is no CDN or DDoS layer in front of `mcp.ankr.com`. **The in-app bucket on +the management plane and the 20-message batch cap on the data plane are the only +bounds that exist anywhere in front of either service.** Whether that is +acceptable, and whether the answer should be an Istio local rate limit rather +than more app code, is item 1 of section 6. + +### 4.9 The payment initiators carry no second factor, and that is the decision + +`mgmt_deposit_with_card` and `mgmt_subscribe_recurrent` are not gated by a +server-verified TOTP, and will not be. This is an accepted risk with a stated +reason, not an unclosed finding. + +**What the tools actually do.** Neither moves money. Each asks the gateway to +create a Stripe **hosted Checkout session** and returns the checkout URL +(`src/mgmt/tools/paymentWrites.ts`). Nobody is charged until a human opens that +URL in a browser and completes Stripe's own form, entering card details and +whatever step-up the issuer requires. The agent never sees, holds or transmits +card data, and cannot complete a payment by any sequence of tool calls. The worst +outcome available to a prompt-injected agent on these two tools is the production +of a link. + +**And it is not even that, today.** Both initiators sit behind the shim's HITL +gate, and since the SHARK-3381 rework that gate is not something an agent can +satisfy: `/confirm` no longer accepts the agent's shim JWT, approval requires a +fresh interactive UAuth login plus a one-time `consentTicket` and a +browser-binding cookie, and the `confirmToken` is bound to `{action, argHash, +sub}` and verified once. So a human already stands between the model and the +link, and a second human step stands between the link and any charge. + +**Why a TOTP on top is refused.** It would gate the act of producing a URL, which +is not where the money is. It buys no security, because the payment is protected +at Stripe by a step the agent cannot perform. It costs product: the gateway lets +an account without 2FA enrolled through by design, so mandating a code at the shim +would make top-up unreachable for exactly those users, and it would put a live +second factor into an agent conversation, which is worse than the thing it +purports to protect. + +**SHARK-3392 recorded two gaps, and only one of them was declined.** Its part 1, +the `/confirm` self-approval path, **shipped**: that is the rework described +above, and the reviewer confirmed it on PR #6 on 2026-07-23. Its part 2, the +server-verified TOTP, is what this section declines. The ticket is closed +Won't Do, which is accurate about the decision and misleading about the half that +was built, so it now carries a comment saying which is which. + +**What this acceptance does not cover.** It is about the payment initiators. The +destructive writes on this plane (create, freeze and edit key, the allowlist +writes, notification suppression) are gated by the same HITL token and no TOTP +either. That is a separate judgement and it rests on the same rework: the gate now +demands a credential the agent does not have. Two of them, key delete and +allowlist edit, additionally land on the gateway's MFA subrouter and do get a +gateway-verified code when the account has one enrolled. + +--- + +## 4b. What production actually runs (read 2026-08-06, re-read 2026-08-07) + +`deploy/` and the two Helm charts on the `deploy/*` branches describe three +different deployments, and production is none of them. Read this before believing +any deployment claim in this repository, including several these notes made. + +**What changed on 2026-08-07, and it changes the shape of this section.** The +routing, the TLS certificate and the signing secret are no longer undocumented: +they are committed YAML in `w3tech/infrastructure-k8s`, and they are quoted below +rather than described. So the old summary "production matches no manifest +anywhere" is now half wrong. It matches manifests, just not the ones in THIS +repository. What survives, and is stated precisely at the end of this section, is +that this repository shipped artifacts describing deployments nobody runs. Two of +the three are now gone: the draft nginx Ingresses were deleted on 2026-08-07, and +the two per-plane Traefik charts are superseded by the merged chart, which carries +no ingress template at all and requests 256Mi for the data plane by default. What +remains is the two superseded chart branches themselves, which should be retired +rather than left to be picked up by mistake. + +**What is deployed. This changed again on 2026-08-07 at about 13:45 UTC, after +most of these notes were written, and the shape below is the current one.** The +two separate ArgoCD applications were replaced by ONE: +`aapi-do-fra1-03-agent-rpc-mcp-production`, project `aapi-production`, Synced and +Healthy. A single Helm release now brings up both pods, and the two old +applications are gone. + +So routing is **Istio**, the signing key is an **ExternalSecret** reading a +stored Vault value rather than a `Secret` minted at deploy time, and images come +from **ECR**. + +The source of truth is **`w3tech/infrastructure-k8s`**, now at the single path +`argocd/apps/aapi/resources/agent-rpc-mcp/`, holding `common/common.values.yaml` +plus a per-cluster directory (`do-fra1-03`). The chart itself is +`charts/agent-rpc-mcp` on the `deploy/mcp-helm` branch of THIS repository, which +supersedes the two per-plane chart branches. This repository's own source tree +does not reference the deployment repository once. + +**The images did not change with the chart merge.** `common.values.yaml` still +pins data to `e9a0b572…` and mgmt to `9176d12c…`, and `initialize` still answers +`0.2.0+e9a0b572…` on the wire, so the code under review is the code serving. + +**One regression came with the merge, and it is the kind worth studying rather +than just fixing.** The merged chart labels its Services only under +`spec.selector`, which selects PODS. A `VMServiceScrape` selects SERVICES by +their own `metadata.labels`, and those were dropped. So from about 13:45 UTC +neither plane has been scraped: `up{namespace="agent-rpc-mcp"}` returns no series +at all, and `mcp_ankr_build_info` is absent, which means "which build is running" +stopped being answerable from a dashboard on the same day it started being +answerable. **The pods stayed Healthy, ArgoCD stayed green and traffic kept +flowing throughout**, which is exactly why nothing paged and why this was found +by hand. Fix in PR #35 (`metadata.labels` on both Services, rendered from the +same helper the selector uses so they cannot drift apart again, verified by +rendering both ways rather than by reading), and it needs `helmChartVersion` +re-pinned to `0.1.1` to reach the cluster. + +The lesson for a reviewer is not about Helm. It is that an observability outage +is invisible to every signal a deployment normally offers, so the only thing that +catches it is an alert on the absence of the metrics themselves. SHARK-3608 +contains exactly that alert, `McpNoScrapeTarget` = `absent(up{namespace="agent-rpc-mcp"})` +for 10m, and it is unmerged in `infrastructure-observability` #310. Merging it is +worth more than the fix it would have caught. + +**The routing, quoted rather than described (re-read 2026-08-07 evening).** It +lives in `argocd/apps/aapi/resources/agent-rpc-mcp/do-fra1-03/certs/istio.yaml`: + +- One **Gateway**, `aapi-mcp-server-gateway`: HTTPS on 443 for host + `mcp.ankr.com`, TLS mode SIMPLE, credential `mcp-ankr-com-tls`, which a + cert-manager `Certificate` in `istio-ingress` issues off the Route53 cluster + issuer. +- **One VirtualService**, `agent-rpc-mcp`, carrying both routes in order: a first + rule matching `uri.prefix: /rpc` to `agent-rpc-mcp:3000`, and a second rule with + no match block at all to `agent-rpc-mgmt-mcp:3100`. No rewrite on either, which + is why the app serves `/rpc` unmodified. + +**That single VirtualService is a fix, and it is worth knowing what it fixed.** +Until 2026-08-07 the same two routes lived in two SEPARATE VirtualServices bound +to the same host and gateway. Istio merges those, and the order of routes +contributed by separate resources is not something either file could state. The +data plane answered only because the specific `/rpc` prefix happened to be +evaluated before the management plane's catch-all; had that order ever flipped, +every `/rpc` request would have landed on the management plane and answered 401, +with both files still looking correct. The SRE who owns the mesh confirmed the +ordering is not guaranteed and collapsed both routes into the single resource +above, where evaluation order is written order. **Verified as shipped, not merely +agreed**: the manifest quoted here is the one now in `main`. + +**The signing key is fixed, and the manifest says how.** `do-fra1-03/secrets/external-secret.yaml` +reads property `gateway-jwt-private-key` from ClusterSecretStore +`vault-k8s-kv-store` at `aapi/mgmt-mcp-server`, `refreshInterval: 1h`. It READS a +stored value; it does not generate one. So the key survives a deploy and a +resync, and the failure mode section 6 used to worry about (every live session +dying at once on a rotation that looks like an auth bug) does not arise unless +the Vault value itself is changed. + +**CORRECTION, same day, second pass. An earlier version of this section named +`argocd-mrpc`. There is no such repository** (the GitHub API answers 404). That +name came from comments inside the Helm charts on the `deploy/*-helm` branches +and was repeated here without being checked, which is precisely the failure mode +the rest of these notes document.

It reads a + stored value rather than generating one, so the key survives deploys and + resyncs (4b). +- ~~bring the two planes back to one commit~~ DONE. `src/` is byte-identical + between the two RC branches, and both images were rolled together in + `infrastructure-k8s` PR #2093. +- ~~the Gateway and VirtualService as applied~~ HALF ANSWERED, and the half that + is answered is now quoted in 4b rather than described. `X-Forwarded-For` is + settled enough to stop asking: the per-cluster values set `TRUST_PROXY_HOPS: "1"` + explicitly, which matches the code default. The route-timeout half is answered + below. + +**Nothing in this section is still open.** The last item was edge rate limiting, +and it closed as a decision on 2026-08-07 rather than as a discovery. + +**Edge rate limiting: DECIDED, do nothing now, revisit at a named point.** +Nothing bounds either plane at the edge. There is no CDN in front of +`mcp.ankr.com`, and the only bounds anywhere are the in-process per-IP bucket on +the management plane's control-plane routes, the bounded session registry, and +the 20-message batch cap on the data plane. All are per process, which is exactly +enough for one replica. + +The option space turned out to be narrower than assumed, and the assumption is +worth recording because it was ours: an Istio local rate limit is a BLANKET limit +in the sidecar, one bucket for all traffic with no per-client key. It is not a +per-IP control. Per-IP at the edge needs a Global Rate Limit service (Lyft +`ratelimit` or equivalent) with a Redis backend that Envoy calls over gRPC on +every request, which is real infrastructure and a per-request network hop. + +**The decision, taken jointly with the SRE who owns the mesh: neither, for now.** +The Global service is disproportionate to current traffic, and the abuse shapes +that actually worried us are already bounded in the application. A blanket limit +was considered as a pod-protection backstop and deliberately not taken either. +**The named point to revisit is the same one 4.2 states: before GA, or when +either plane moves past one replica, whichever comes first.** A reviewer who +thinks that is the wrong call should say so here rather than in the code, because +nothing in this branch would change. + +**The route timeout is settled, from both ends.** Our measurement is below; the +SRE confirmed independently that no timeout is set on the Gateway, so there is no +max-duration cap from the mesh side at all. + +**The two-VirtualService risk is CLOSED, and shipped the same day.** The SRE +confirmed the ordering between separate VirtualService resources is not +guaranteed and collapsed both routes into one resource, together with merging the +two applications into a single chart. Both are in `main` and running; 4b quotes +the manifest as applied. + +**One thing arrived with that merge, and it was fixed the same afternoon.** The +merged chart dropped `metadata.labels` from both Services, so the VMServiceScrapes +matched nothing and neither plane was scraped between about 13:45 and 14:32 UTC. +Fixed in PR #35, chart 0.1.1, re-pinned and rolled. **Verified as recovered, not +reported as recovered**: `up{namespace="agent-rpc-mcp"}` is 1 for both jobs and +`mcp_ankr_build_info` again carries `e9a0b572…` and `9176d12c…` on new pods. 4b +records what the episode says about which failures are visible. + +**The route timeout on long-lived streams was the second item here, and it was +settled by measurement rather than by asking.** Neither VirtualService sets +`timeout`, so the mesh default applies and nobody had read it. The worry was that +`GET /rpc` and `GET /mcp` are SSE streams which can sit idle between messages, and +a stream cut by a default timeout looks to an agent like the server going quiet +rather than like an error, which is the worst shape a failure can take here. + +Measured against production on 2026-08-07 by holding `GET /rpc` open and reading +it a byte at a time: + +- the stream survived **22.2 minutes** and was not cut, so there is no hard + max-duration cap below that; +- and it was never idle. The wire carries `: keepalive\n\n` about every 15 + seconds, so a mesh idle timeout of any value above 15s cannot fire. + +**Read the second finding as a dependency property, not as a decision anyone +made.** The keepalive comes from the MCP SDK's +`WebStandardStreamableHTTPServerTransport` (1.30.0), which the Node transport both +planes import is a thin wrapper around. It is not our code and not the mesh's +configuration, so an SDK upgrade that drops or lengthens it silently reopens the +question.

Before this, freezing such a key cost TWO human approvals — `mgmt_reveal_api_key` to obtain the token, then the freeze — so the reversible action required performing the credential-disclosing one first, the consent page with real blast radius was the one people clicked as a stepping stone, and every key an operator touched left a live RPC credential in the transcript. It is now ONE approval, on the action the human actually wants, and the page names the key by slot and name.

The remaining limit, and why it is a limit rather than an omission: attaching a NAME to a masked token still costs one reveal approval (or the console). The gateway keys spend by endpoint token while `GET /auth/jwt/all` identifies a project by slot index and carries only `jwt_data`, a different credential; converting one to the other is the worker exchange sent with `createNew: "yes"`, which this shim has not verified to be idempotent and must not run per key from a tool annotated read-only. So the reply carries the slot+name roster the key list CAN give, states that it cannot say which masked token is which, and refuses to pair the two lists by order (the account-level key spends here too and is not a project slot) | + +## 4.

Checkout URL, `mgmt_card_payment_eligibility` says up front whether the account may use one. **Correction (SHARK-3571): it said the opposite of the truth to every account until this ticket.** The route answers `{isEligible}` (protojson default names) and the shim read `is_eligible`, so the flag was never true and the tool replied "This account is NOT eligible for card (Stripe) payment" to everybody. It is normalised at the client boundary now, both spellings accepted, and an ABSENT flag is a third answer rather than a NO: the tool says the gateway did not report it instead of telling a paying customer they cannot pay. The agent cannot charge anything; a human completes payment. Matches QuickNode and Alchemy, neither exposes autonomous fiat | +| 4.3 | Start or read a subscription | **DONE** | `mgmt_subscribe_recurrent`, `mgmt_get_subscription_prices` (which had the same wire-shape defect as row 4.2 and answered "No subscription prices available" whatever the gateway held; the reply is `{productPrices: [...]}` with `intervalCount` as a protojson string, and it is normalised at the client boundary now), and, since SHARK-3571, the BUNDLE half of the same capability: `mgmt_list_bundles` (the catalog, with the product and price ids a purchase needs) and `mgmt_subscribe_to_bundle` (a Stripe Checkout link, HITL-gated exactly like the recurring initiator). `mgmt_get_subscriptions` READS BOTH KINDS and labels each row with which it is. **Correction (SHARK-3571): this row said DONE while half of it was missing, and the missing half was reported to customers as a fact about their account.** The listing read only `GET /auth/payment/getMySubscriptions`, which never contains bundles (the gateway serves those from `GET /auth/myBundles`, and `bundle_controller.go` resolves it against the same account), so a bundle holder was told they had no subscriptions. That is the failure mode the second rule at the top of this file is about: nobody had read the bundle route inventory. Two honest limits are stated rather than papered over. A list that FAILS to read is reported as unreadable next to the list that did read, because "the bundle route is down" and "you hold no bundles" are different answers and only one of them can be true; and `SubscribeToBundleRequest.resubscribe` is sent as `false` and is NOT exposed as an input, because what the gateway does with `true` is not documented anywhere we have read and a guessed flag on a payment is worse than an absent one. Renewing an existing bundle therefore stays a console action, recorded here as a known limit rather than attributed to a ticket nobody has filed **Correction (SHARK-3571, found by this branch's own adversarial review): the sentence above was true of the intent and false of the code.** `mgmt_get_subscriptions` rendered `No active subscriptions or bundles.` whenever nothing was held, which included the bundle list having failed, the recurring list having failed, and BOTH having failed. The unreadable-list qualifier was appended AFTER it, so the absence was still asserted first, in the words a customer reads, which is the SHARK-3571 defect standing in a different place. The absence is now scoped to the lists that actually answered (`absenceSentence`): one list dead names only the kind that WAS read, and both dead says the answer is empty because neither list could be read rather than because the account holds nothing. `_meta.unreadable` carries the same fact as a list of kinds, for a client that branches on flags rather than on prose, which is the reason the sibling notification work carries `_meta.connected`. Separately, a money AMOUNT that arrived as a JSON number was DROPPED by the wire readers and rendered as `?`, and the cancel approval page said `an unreported amount`: `optString` accepted only strings while `interval_count` in the same object literal accepted both encodings. The amount on a subscription, on a catalogue price and on a bundle offer, plus the ledger's `amount_usd` and `amount_ankr`, now read through `optWireString`, which takes either encoding and returns a string's exact characters so the decimals are never reformatted | +| 4.4 | Cancel a subscription | **DONE** | Ships in SHARK-3546. `mgmt_cancel_subscription` wraps `POST /auth/payment/cancelSubscription` (body `{subscription_id}`), HITL-gated. The old GAP's stated reason was wrong in the way the second rule at the top of this file warns about: no server-verified TOTP path is needed, because the gateway is the MFA authority and the shim simply FORWARDS `totp` as `x-ankr-totp-token`, exactly as it already does on the other MFA-gated routes. **Correction (SHARK-3584): there are SIX such routes, not three, and this row used to name two.** The list was read straight off the gateway's `mfa.go` `targetList` instead of being inferred from the console's client: `DELETE /auth/jwt`, `PATCH /auth/whitelist`, this route, `POST /auth/token/custom/new`, `POST /auth/token/custom/delete` and, added by SHARK-3578, `POST /auth/abstractBindings/unbind`. (The count read FIVE here until SHARK-3570; the sixth had shipped in `MFA_GATED_ACTIONS` and was recorded only in row 6.8.) The code also no longer has to come from the caller: on an account with 2FA the approval page asks the human for it (row 6.6). SHARK-3392 stands unchanged: the shim neither mandates nor verifies the code, and an account without 2FA is let through by the gateway. The approval page states WHAT stops being charged (that subscription's amount, currency and billing period, read from the account's own record rather than from the caller's arguments) and FROM WHEN (no further payment for THAT subscription; the period already paid for runs to its `current_period_end` and is not refunded), plus what does NOT stop (other subscriptions, and pay-as-you-go usage). Two honest limits, both stated to the caller instead of guessed: the route answers with an EMPTY body, so the reply reports that the request was ACCEPTED and points at `mgmt_get_subscriptions` rather than claiming Stripe's resulting state, and nothing tells us whether the gateway ends access at once or lets the paid period run out. An id the account does not hold is refused before any human is asked to approve anything; one that disappears between the approval and the call is refused rather than reported as cancelled **Extended (SHARK-3571): it cancels BOTH kinds, and it picks the route on evidence.** The pre-flight now reads both lists and the id is cancelled through the route whose list it was actually in: `POST /auth/myBundles/unsubscribe` for a bundle, `POST /auth/payment/cancelSubscription` for a recurring one, which is the same branch the console makes in `useSubscription.ts`. Worth recording because it reads as stronger than it is: at multirpc-accounting-gateway 470f9a4 `router.go` points BOTH paths at `paymentController.CancelSubscription`, with the same body and the same acl roles, so sending a bundle to the payment route would not today cancel the wrong object. The evidence-based pick is there because the shim must not tell a customer "bundle" while calling the payment route, and because the two routes are free to diverge. The refusal that opened SHARK-3571 is gone in both directions: an id in NEITHER list is still refused before any human is asked to approve anything (and the refusal now lists both kinds' ids), while an id that is merely unfindable BECAUSE a list could not be read is no longer refused at all: the gateway, which can see both lists, is the authority. The approval page names which kind it is only when the lookup found it; when it did not, the wording stays neutral rather than guessing "recurring" at somebody holding a bundle. `_meta.subscription_kind` carries the same answer for a machine reader. **Correction (SHARK-3571 follow-up, found by this branch's own adversarial review): the unreadable-list reason was computed and DISCARDED.** `findSubscription` built a " list: " string for the case where a list could not be read, and no caller ever read it, which is why mutation could delete it, empty its `.map` and drop its `join("; ")` with the suite green: there was no surface to observe it on. It now reaches the APPROVAL PAGE, which is where it belongs. A human is being asked to approve a cancel on an object this shim could not identify, and "its amount and billing period could not be read" does not tell them whether that is an empty account or a gateway that is down. The tool still does not refuse in that case, which is unchanged and deliberate: the gateway can see both lists and is the authority. Separately, the page's five effect statements are now pinned WHOLE by a test rather than matched with loose alternations, because this row is DONE almost entirely on what that page states and mutation showed every sentence of it, including the widened UNAFFECTED_EFFECT, could be emptied one at a time without a failure | +| 4.5 | Read invoices | **DONE** | `mgmt_list_transactions` + `mgmt_get_invoice_details`. **Correction (SHARK-3575): this row said DONE while the tool it named could not be called.** `mgmt_get_invoice_details` requires a `txId`, `GET /auth/transactionHistory` was not wrapped, and no other tool in the set returns a transaction id, so the only way to reach the invoice read was to find the id in the console, where the document is one click away anyway. A capability that needs an argument nothing can produce is not shipped, and the row is the second rule at the top of this file failing in the other direction: nobody had walked the chain. `mgmt_list_transactions` wraps that route and closes it. It lists the account's billing ledger over a window with the paging the route supports (cursor plus limit), and renders each row as the thing a customer recognises: date, kind, amount and currency, plus the chain and the free-text reason where the route carries them. Three things are read off the route rather than assumed. It has no currency FIELD, so which of `amount_usd` / `amount_ankr` is populated is the currency, and both are shown when both are; its `type` is a proto enum that arrives as a member name from one responder and as an ordinal from another, so both are decoded and an ordinal outside the set is reported as unknown rather than mapped onto the enum's own `UNKNOWN` member; and it carries NO API key or project, so the listing does not pretend to attribute a charge to one. `from` and `to` are the route's only required parameters, so the tool defaults a 30-day window and always states the window it sent, in ISO and in raw milliseconds, which is what makes an empty page diagnosable instead of reading as an account with no history. The `type`, `order_by` and `sort` filters exist on the route and are deliberately NOT plumbed: nothing we have read says whether `type` wants `DEPOSIT` or `TRANSACTION_TYPE_DEPOSIT`, and a filter that silently matches nothing would report an empty ledger to a customer who has one, which is the failure this ticket is about. One known limit, stated in the tool text rather than returned as a blank that reads like an error: a card payment has Stripe documents behind its transaction id, and a crypto deposit has none. The gateway generates that one through `GET /auth/document/invoice/cryptoDeposit`, which requires the on-chain transaction hash and a billing name; `proto.Transaction` carries neither, so it cannot be driven from a listed row and stays a console action. When both URLs are absent `mgmt_get_invoice_details` now says which situations produce that (a crypto deposit, or a card payment whose documents Stripe has not published yet) and that the gateway did answer **Correction (SHARK-3575, found by this branch's own adversarial review): the chain was closed for ONE of the two document types.** `mgmt_get_invoice_details` takes `txId` AND `txType`; the listing produced only the id, and the listing's own guidance hardcoded `(txType DEPOSIT)` for every row. A bundle purchase reaches this ledger as a `DEDUCTION` and its Stripe document is filed under `BUNDLE`, so following that guidance answered "no Stripe document, probably a crypto deposit" while the invoice existed one enum value away. The two vocabularies are unrelated and nothing we have read maps between them: the ledger's `kind` is `proto.TransactionType` (DEPOSIT, DEDUCTION, WITHDRAW, BONUS, COMPENSATION, VOUCHER__, WITHDRAW__, with NO `BUNDLE` member) while the document selector is `StripeDocumentType` = DEPOSIT or BUNDLE, so deriving one from the other would be exactly the guess the second rule at the top of this file forbids. `txType` is therefore OPTIONAL and the tool SEARCHES: omitted, it asks for DEPOSIT and then, only if that answered with no document, for BUNDLE, and it names the type that held the document both in the reply and in `_meta.tx_type`. A probe that FAILS is not a verdict on its type, so the other one is still tried; when NEITHER type answers at all the reply is an error rather than a claim that no document exists. The empty-result note is now honest in both directions: after a search it states that both types were asked and the type is therefore not the reason, and when the caller pinned a type it names the THIRD situation the shipped wording omitted (the document may be filed under the other type) together with the value to pass instead **Production caveat (SHARK-3593), and it is not this branch's to fix.** This row is DONE on the legend's terms, pinned by test and by live run, and it still FAILS in production on at least one account: the gateway answers 504 deadline_exceeded on `GET /auth/transactionHistory` for a large ledger, whatever window is asked for. So `mgmt_list_transactions` returns the route's error rather than a ledger, and the invoice read behind it is unreachable for that account.

So the "shows 7" limit is gone. What keeps this PARTIAL is a different thing, and it is the one stated to the caller: the read is the gateway's DEPRECATED ACCOUNT-LEVEL endpoint while the write is PER-CHANNEL (EMAIL / TELEGRAM / SLACK / INAPP), so a per-channel write may legitimately not appear in that read; `mgmt_get_notification_channels` is the per-channel read-back. SHARK-3523 | +| 5.4 | Enable / disable / delete a delivery channel | **DONE** | `mgmt_get_notification_channels`, `mgmt_set_delivery_channel_status`, `mgmt_delete_delivery_channel`. **Corrections (SHARK-3579 follow-up, found by this branch's own adversarial review), both about the repair a customer is sent to.** (a) The READ-BACK RULE now reaches `mgmt_set_delivery_channel_status` on the ENABLE direction. Enabling asks for the channel to become usable NOW, which is exactly what `expectActive: true` means in `channelActivation.ts`, and this is the tool `mgmt_get_slack_connection` tells a caller to run to resume delivery, so answering it with "the request was ACCEPTED" put the caller back in the defect SHARK-3579 exists for: they believe alerts resumed while nothing is delivered. Six call sites got the read-back when that rule landed and this seventh, sitting on the remediation route, did not. The DISABLE direction deliberately KEEPS the accepted-not-observed wording: `renderActivation` answers "is this channel usable", so on a disable its active branch would print "as ACTIVE, so alerts will be delivered there" as though that were the goal, and asserting the negative needs its own contract rather than a reused one. (b) `mgmt_get_slack_connection` prescribed ONE repair for the two ways Slack can fail to deliver: an account with the bot in a Slack channel but NO SLACK row was told to "re-enable the SLACK channel", which cannot work because enabling does not create a row, while the two tools that do create one (`mgmt_start_slack_connection` then `mgmt_integrate_slack`) went unnamed.

| +| 6.1 | Know which account I am acting on | **DONE** | `mgmt_whoami` returns the address of the account the login owns, plus the team account the session is acting on when one was selected, as two separate facts. Every account-scoped result names the account it applied to, and the approval page shows the same value. Three results carry no account line, each for a stated reason: a refusal or an error (nothing was applied), a needs-approval reply (the account belongs on the consent page, where a human checks it), and the account-independent price catalogue. The line is otherwise unconditional, and which tool gets one is decided by the TOOL NAME, never by searching the rendered result for the address: until SHARK-3563 it was a substring test, so a write whose own argument was the account address (`mgmt_add_allowlist_item` with `item: `) landed with no account statement at all | +| 6.2 | Choose which account to act on when I have several | **DONE** | Ships in SHARK-3552. `mgmt_list_accounts` enumerates what this login can act on from `GET /auth/group` (address, name, `user_role`, enterprise / freemium / suspended, seat counts) with the personal account included and stated to have no role. `mgmt_select_account` aims the session at one of them, and every account-scoped call then carries `?group=
` on the SAME bearer, with no second sign-in. The parameter is applied in ONE place (`request()` in `src/mgmt/gateway/client.ts`, from the session `AccountScope`), so no tool can forget it, and the verified route list lives in `src/mgmt/gateway/groupScope.ts`. An address this login holds no seat on, and an account list that cannot be read, both REFUSE and leave the session where it was: there is no fallback to the personal account. The SHARK-3544 safety net still bites and now measures against the account in force, so after selecting a team account a call pinned to the personal one is refused before the gateway is called. A human approval cannot follow the session across a selection either (SHARK-3552, hardened by SHARK-3562): the pending confirmation records the `?group=` in force when it was minted, and a token whose recorded account is not the one in force is refused before the gateway is called and WITHOUT being consumed, so it stays valid for the account it was granted for. The binding is the group parameter rather than the address rendered on the consent page, because that address comes from `GET /auth/users/profile` and used to be absent exactly when the read failed — which stood the check down and left the approval spendable anywhere. The address is still checked as a second statement of the same fact, and now fails CLOSED: an approval that names an account is refused while the account in force cannot be read. The route list itself is now PINNED entry by entry (SHARK-3564). It had 100% line, branch and function coverage and a 32.61% mutation score, which means any single one of its entries could be deleted without a test failing: the table that decides which account a call lands on was, in the only sense that matters, unasserted. `test/mgmt-group-scope-table.test.ts` writes every route out as a LITERAL in the test rather than reading them from the set under test (a test that derives its expectation from the table passes whatever the table says), asserts each one is accepted, asserts the set holds exactly those and nothing more, and pins the size so a one-line addition breaks a test and has to be justified. Both directions are failures and both are now covered: a MISSING entry refuses a route that really does support the team account, while an EXTRA entry is the leaking one, sending `?group=` to a route that ignores it so the gateway answers for the personal account while the transcript names the team. The refusal sentence is asserted as one exact string, so no clause of it can quietly vanish. **The table now holds 56 entries** (`GROUP_SUPPORTED_ROUTES.size`, pinned as a literal 56 by the test; it was 31 when this row was written and every addition since had to justify itself against that assertion). The file scores **100.00, re-measured at SHARK-3570: 75 mutants, 73 killed plus 2 timed out, 0 survivors**, against the break threshold of 60. The previous figure quoted here, 46 of 46, was measured when the table was smaller and is not a number that can be carried forward — a bigger table means more mutants, so the score has to be re-run rather than inherited. Which account a session STARTS on is a different question from which one it moves to, and the data that makes it predictable is row 6.8: a login resolves to an address through the method it signed in with, so `mgmt_list_login_methods` and `mgmt_list_login_addresses` are what explain a re-login landing somewhere unexpected before `mgmt_select_account` is reached for | +| 6.3 | Act on a team / group account | **DONE** | ACTING on one ships (SHARK-3552): keys (list, create, edit, freeze, delete, reveal), allowlists, balance and spending reads, notifications and payments all carry `?group=` and act on the selected team account, and its own account-level key resolves through `GET /auth/group/jwt?group=` plus the worker exchange (`mgmt_reveal_api_key` slot 0, which stays refused on a personal account because the personal route for it is behind a second factor). One limit, stated to the caller rather than silent. **(a) is CLOSED as of SHARK-3587, and it was closed by reading the gateway rather than by asking anyone.** Four reads used to refuse under a team account on the grounds that the console never passes `group` to their routes, so whether they honoured it was unverified. That was a fact about our evidence, not about the route: `src/route/router.go` in w3tech/multirpc-accounting-gateway (commit 470f9a4) registers all four on `groupSupportedRouter` (lines 267-269, 270-272, 279-281 and 381-383) and each has its own row in the `acl` map of `src/middleware/groupacl.go`. So `mgmt_get_usage` (`/auth/intervalUsage`), `mgmt_get_interval_stats` (`/auth/stats`), `mgmt_get_days_estimate` (`/auth/numberOfDaysEstimate`) and `mgmt_get_notification_config` (the deprecated `/auth/notification/configuration`) now carry `?group=` and answer for the selected team account like every other scoped read; deprecated is not the same as unscoped. Refusing them had been telling a customer their own team's usage and runway were unavailable when the gateway would have served them all along. **(b) is CLOSED as of SHARK-3554.** MANAGING a team ships in full: create, seat eligibility, rename, batch invite, cancel, resend, the invitee's own list plus accept and reject, change a member's role, remove a member and leave. All thirteen routes are wired, and the family is split by SUBJECT rather than by convenience: eight are about ONE TEAM and carry `?group=`, five are about the LOGIN and pass `group: null`. See section 8. What remains is pinned rather than merely described (SHARK-3564, re-keyed by SHARK-3587): the verified route set is asserted entry by entry against literals, and a call refused under a team account is asserted to have reached the gateway not at all, so a refusal cannot decay into a request that quietly answers for the personal account. **SHARK-3587 also changed the KEY of that set from PATH to METHOD plus PATH, which is the structural half of the fix.** Go registers a handler under a method AND a path, and the gateway's own group ACL keys its lookup as `fmt.Sprintf("%s %s", r.Method, r.URL.Path)` (`groupacl.go:579`), so a path-keyed allowlist let one verb inherit a sibling's evidence: `/auth/jwt` is account-scoped for DELETE and for nothing else, and `/auth/whitelist/mode` was in the set on the strength of the console's PATCH while the GET rode along unexamined. The GET turned out to be scoped too (`router.go:617-618`), so nothing leaked, but the reasoning could not have told us that. The allowlist is now keyed the same way the gateway keys it, and a verb the gateway does not register cannot borrow one that it does. SHARK-3586 closed the third direction the table can fail in, which neither limit above describes: a route that is neither allowlisted nor explicitly opted out with `group: null` REFUSES while its own tools promise team support. Every gateway method is now classified and asserted one by one in `test/mgmt-account-scope-completeness.test.ts` (**55 account-scoped, 18 login-scoped, 3 refusing, 76 in total** as of SHARK-3575, each row carrying its HTTP verb since SHARK-3587; the split was 41/10/3 when this row was written and the test pins the current one), which is what makes the limit above the complete list rather than the known part of it. The three that still refuse are the Platform API key trio, and their reason survived the read and got stronger: they are on `secureMfaRouter`, a child of `secureRouter` and not of the group router, so a `?group=` there is not rejected but silently IGNORED and the gateway answers for the credential's own account | +| 6.4 | Log in from a client without pasting a token | **PARTIAL** | OAuth 2.1 shim with the real browser UAuth login works end to end. Limit: the DCR client registry is in-process, so a redeploy invalidates every registered client and the next call fails `invalid_client: Unknown client_id` until the client re-registers. SHARK-3547. **Correction (SHARK-3574): OAuth is not the only headless path, and this row used to read as though it were.** The console's answer for a client that cannot open a browser at all is a Platform API key, not OAuth, and that is the "API key for CI" the Sources paragraph above benchmarks QuickNode on. It ships as row 6.5, so a CI job needs neither a browser nor a client registry that survives a redeploy | +| 6.5 | Give a headless client its own credential | **DONE** | Ships in SHARK-3574. `mgmt_create_platform_api_key` mints a Platform API key — a bearer for the MANAGEMENT API itself, over `POST /auth/token/custom/new` — so CI, a cron job or an agent can call the gateway with no browser login; `mgmt_list_platform_api_keys` shows the handles (`GET /auth/token/custom/all`) and `mgmt_delete_platform_api_key` revokes them (`POST /auth/token/custom/delete`). All three are read off the console's own client, and both writes forward a TOTP. SHARK-3584 then VERIFIED that forwarding against the gateway rather than leaving it on the console's evidence: both `POST /auth/token/custom/new` and `POST /auth/token/custom/delete` are `true` in `mfa.go`'s `targetList`, so on an account with 2FA the approval page asks for the code and carries it into the call (row 6.6). It is NOT an RPC endpoint token and the tools say so: it administers the account rather than fetching chain data, and it carries the whole of this surface with no further human approval — which is exactly what the approval page tells the human before they grant it. Four consequences of that, enforced rather than documented: `ttl_sec` has a schema maximum of 31536000 (365 days, the longest validity the console's own dialog offers), so one approval cannot mint a credential that outlives everyone in the conversation; the bearer is delivered exactly ONCE, in the mint reply, and reaches no log, no `_meta`, no consent page, no error message and not the listing (five surfaces, each pinned with a fixture the generic secret-masking net cannot catch, because a key-shaped fixture would let a pass-through tool look safe); the listing is a PROJECTION of handle, name and dates, so it stays free of credentials even if the route ever grows one; and a reply whose bearer sits under a field name the shim does not read is reported as a contract failure WITHOUT echoing the body, naming the list and revoke tools so a key that may exist can still be found and killed. Two limits, both stated to the caller. (a) None of the three routes takes an account parameter — the console passes none — so all three REFUSE while a team account is selected, before any approval is minted, and the refusal says it is a limit of the route rather than of the caller's seat; the per-route evidence is recorded in `src/mgmt/gateway/groupScope.ts`. (b) There is no rename and no rotate: the gateway offers neither, so replacing a key means minting a new one and revoking the old | +| 6.6 | Complete an action my account's second factor protects | **DONE** | Ships in SHARK-3584 (status read: SHARK-3576). **Six** of the routes this shim calls are on the gateway's MFA middleware — `DELETE /auth/jwt`, `PATCH /auth/whitelist`, `POST /auth/payment/cancelSubscription`, `POST /auth/token/custom/new`, `POST /auth/token/custom/delete` and `POST /auth/abstractBindings/unbind` — and on an account with 2FA each refuses a request carrying no code. (SHARK-3570: this row said five and omitted the unbind, which SHARK-3578 had already added to the table and recorded in row 6.8 as the sixth; `MFA_GATED_ACTIONS` in `src/mgmt/tools/twoFactor.ts` is the one list, and it holds six.) Nothing used to ask for one: the tools took an optional `totp` nobody filled, so a human spent a real approval (a browser login and a deliberate click) and the gateway then answered with a raw `HTTP 400 {"error":{"code":"2fa_required"}}` they could not act on. **The code is now asked for on the APPROVAL PAGE**, from the human who is already standing at their authenticator, and carried into the write server-side; it never reaches the model, in the needs-approval text, in `_meta`, in the rendered page or in an error. The alternative — having the agent prompt for it — was rejected outright: it would put a live second factor in a chat transcript and make the agent the thing that holds it. Whether to ask is decided from `GET /auth/2fa/status`, also exposed as the read-only `mgmt_get_2fa_status`; a definite answer is cached for 5 minutes rather than for the session, so a user who hits this wall, goes and enrols and comes back is asked for a code on their next attempt instead of hours later; **a status that cannot be read means POSSIBLY ON, never off**, so the page asks and accepts an empty answer rather than letting one bad status read block every gated write on accounts that have no second factor at all. A blank or mistyped code re-asks on the same page (bounded, and hard-bounded by the approval's own 5-minute TTL) instead of costing a fresh browser login, and approves nothing meanwhile. When the gateway does refuse with `2fa_required` or `2fa_wrong`, the reply says which of the two it was and what to do next instead of surfacing the 400. Whether a route is gated lives in ONE table mirroring `targetList`, not in a flag at each handler, because a handler that forgets the flag simply stops asking — the same silent failure this row exists to fix. **Out of scope by Mike's decision (2026-08-01): 2FA MANAGEMENT.** `POST /auth/2fa/init`, `/confirm` and `/clear` are not exposed, so this surface can see whether a second factor exists and can never enrol, change or remove one; use the console for that | +| 6.7 | See where I am signed in, and end a session I do not recognise | **DONE** | Ships in SHARK-3577. `mgmt_list_sessions` reads `GET /auth/session/ui/all` and names every login open on this account (device, browser and OS, when it was signed in, when it expires) with THIS assistant's own session marked from the route's own `current_session` flag; `mgmt_revoke_session` ends one and `mgmt_logout_other_sessions` ends every other one, both over `POST /auth/session/ui/delete` and both HITL-gated. This is the control a customer reaches for when they think a credential leaked, and it was the one incident-response surface the shim did not have at all — which matters here more than elsewhere, because an MCP session IS one of the logins in that list. **Three of the ticket's acceptance criteria were not true of the product and the honest version shipped instead, each recorded on SHARK-3577.** (a) The listing was to carry IP and last-seen. The route carries NEITHER: `IGetAllSessionsResponse` is exactly token_key / created_at / expires_at / current_session / creation_details, and `creation_details` is exactly os, os_version, browser, browser_version, device. Rendering `created_at` as "last seen" would be a fabricated security fact on the screen where a customer picks out the intruder, so both absences are STATED on every listing and a test asserts nothing IP-shaped is ever printed. (b) `mgmt_logout_other_sessions` was to wrap `POST /auth/session/ui/logout`. That route is `logoutCurrentSession()` on the console's own client — its name says it ends the CURRENT session, the opposite of the tool — and nothing in the console calls it; the console's "Terminate all other sessions" is a `deleteSessions` over every key except the current one. Wrapping an uncalled route would have shipped a guess about what a security control destroys, so the tool does what the console does and a test asserts the logout route is never contacted. (c) The self-revocation decision: **ALLOWED, with the consequence first on the consent page.** The console refuses it; we diverge because a console user has a logout button three inches away and an MCP caller has none, so if the leaked credential IS this session's bearer then a tool that will not kill it is useless in the one incident it exists for. It is never a side effect: `mgmt_revoke_session` takes ONE session, and `mgmt_logout_other_sessions` refuses outright unless the gateway positively marks a session as this one, because "every other" is not something it will approximate. The session handle is treated as CREDENTIAL-GRADE and never rendered — not in text, `_meta`, logs, errors or the consent page — even though the evidence says it is a handle rather than a bearer (the sibling `/auth/token/custom/*` pair returns `access_token` for the secret and `token_key` for the handle), because the gateway source is not vendored here and being wrong means publishing the bearer of every device the customer owns. Sessions are addressed instead by a `session_ref`: `s-` plus eight hex of a per-process KEYED digest, so it is one-way, cannot be precomputed, and cannot correlate a session across deployments; a ref that resolves to nothing, or to two sessions, is REFUSED before any human is asked to approve anything. The consent page names the session by device and sign-in time rather than by an id. Two limits, both stated to the caller: an entry the gateway returns with no handle cannot be addressed, so it is counted and declared UNENDED on the page and in the result rather than silently dropped from a "terminated everything" claim; and there is no rename, no per-session detail and no session creation here. Neither route takes `?group=` (the console passes no params object to either), but unlike the Platform API key trio these tools do NOT refuse under a team account — a session belongs to the LOGIN, so there is no per-account answer for the parameter to select, which is the same reason `mgmt_get_2fa_status` is login-scoped; all three register on the RAW server and carry no role capability, and the per-route evidence is recorded in `src/mgmt/gateway/groupScope.ts`. **SHARK-3586: for the first release that "do NOT refuse under a team account" was true of this row and false of the code.** Staying out of `GROUP_SUPPORTED_ROUTES` is not opting out — `resolveGroup` still defaults a call to the session's selection — so both routes inherited it, `request()` raised `AccountScopeError`, and under any selected team account ALL THREE tools refused: no listing, no revoke, no bulk logout, the whole incident-response path gone for exactly the customers who have a team to respond on. Four documents, three tool descriptions and one test said otherwise; the test was green because it drove a stub gateway whose `listSessions` never executed `request()`. Both calls now pass `group: null` explicitly, and the guard is not the two-line fix: `test/mgmt-account-scope-completeness.test.ts` walks EVERY method on the gateway client over a recorded fetch and asserts each is account-scoped (sends `?group=`), login-scoped (absent from the allowlist AND still sent with no `group`, reachable only via `group: null`), or refusing with its reason recorded — so a new route cannot land in the silent fourth class again | +| 6.8 | See what can log in as me, and remove a way in | **DONE** | Ships in SHARK-3578. `mgmt_list_login_methods` reads `GET /auth/abstractBindings/list` and names every login method bound to this Ankr LOGIN (the wallet, Google, GitHub or other provider account that can sign in as you, who each one lets in, and whether the gateway allows it to be removed), folding in `GET /auth/abstractBindings/available` so the same answer says which kinds CAN be bound and whether binding is open at all; `mgmt_unbind_login_method` removes one over `POST /auth/abstractBindings/unbind`, HITL-gated and second-factor gated. `mgmt_get_email_identity` reads `GET /auth/email` and `GET /auth/email/active`, and `mgmt_list_login_addresses` reads `GET /auth/googleOauth/getAllMyEthAddresses`. A bound login method is a way into the account: adding one is a privilege grant and removing one can lock a customer out, and this surface previously showed neither, so a customer could not notice a binding they never made and could not remove one. **Two of the ticket's acceptance criteria were not true of the product and the honest version shipped instead, each recorded on SHARK-3578.** (a) `mgmt_bind_login_method` was to wrap the bind route, HITL-gated, with a consent page stating what a bind grants. It is NOT wrapped and no bind tool is registered. The route's body is `IOauthSecretCodeParams` = `{secret_code, state, provider?}`, an OAuth authorization code from the login provider's redirect: the identity being granted access is inside that opaque code and only the gateway can decode it, so the consent page could not name WHO would gain access, which is the one thing that page exists to say. Two lesser reasons hold on their own: the code cannot be obtained from here (the provider redirects to the URL the gateway hands back, which is the console's, and the console consumes the code on arrival), and a `secret_code` argument would teach an agent to ask a user to paste an OAuth code into a chat transcript, which is the defect this repo already refuses to ship for TOTP codes. What the criterion was really owed, telling the customer what a bind grants and where it happens, is discharged on the listing and pinned by a test. Wiring the real thing later means a second, provider-facing OAuth leg with an overridden `redirectUrl` plus a gateway-side entry for that URL, which is a feature rather than a line. (b) The last-method decision: **REFUSED, by name, before any human is asked to approve anything.** An unbind that would leave this login with no bound login method is refused with the reason `the last login method`, and the refusal states that this is the shim's rule rather than the gateway's, that it counts only the bindings the list route shows, what it could not read, and the safe order (add the replacement in the console first). This diverges from row 6.7's self-revocation choice deliberately: ending your own session has a real incident-response use, while being left with no way in has none, so a refusal costs a trip to the console and an allow costs the account. Separately and FIRST, the gateway's own verdict is honoured: every binding carries `canUnbind` and `canUnbindReason` and the console disables its disconnect control on exactly those, so a locked binding is refused in the gateway's own words, and ONE locked entry stops the removal because the route addresses a KIND and not an entry. The listing states that the route carries NO date for a binding rather than inventing one, and an entry the gateway returns with no provider is counted and declared rather than dropped, because that count is the denominator of the lockout check. The unbind's own outcome is reported as accepted-but-not-observed: the route answers `{result: string}` whose vocabulary nothing documents, so the string is quoted verbatim, no removal is claimed, and `_meta.observed` is false with `mgmt_list_login_methods` named as the read that settles it. **Second factor:** `POST /api/v1/auth/abstractBindings/unbind` is `true` in the gateway's `mfa.go` targetList, so it is the sixth MFA-gated action and the approval page collects the code; the sibling bind route is absent from that list even though the console sends a TOTP header on both, which is why the table mirrors the gateway rather than its client. **Email identity writes are deferred and the split is stated so neither ticket assumes the other did it:** the two reads ship here, while `POST`/`PATCH`/`DELETE /auth/email/bind`, `POST /auth/email/confirm` and `POST /auth/email/resendConfirmation` ship in neither this work nor the notification-channel work. They are a different thing from the notification email (`POST /auth/notifications/email/enable`, already shipped as `mgmt_add_notification_email`, which is a DELIVERY channel), the confirm chain only completes with a code delivered to a mailbox that the agent would end up holding, and the delete verb is a second lockout path needing the same last-method treatment. **No credential, OAuth code or confirmation token reaches text, `_meta`, an error, a log or a consent page:** the provider's opaque `externalId`, the email reply's `error` object and the address entry's `public_key` are all dropped at the client boundary rather than passed through, and a test plants one of each in a shape the generic 32-plus-alphanumeric masker cannot catch, so a pass-through shows up verbatim instead of looking safe. **Account scope:** none of the six routes is an `IApiUserGroupParams` call site (four take no arguments at all, the unbind takes only `{provider}`, the email list takes only `{filters}`), so none is in the verified `?group=` set and all four tools register on the RAW server and are NOT refused under a team account, for the same reason `mgmt_get_2fa_status` is login-scoped. Each of the six passes `group: null` EXPLICITLY rather than merely staying out of the set, because a route that only stays out still inherits the session's selection and raises `AccountScopeError`; a test drives the real client under a selected team account and asserts all six URLs carry no `group=`. All four tools are capability-free: the console's `AccountPermission` has no entry for the login methods block, and a role cannot govern a login | + +## 7.

It is DONE on the legend's own terms: pinned by `test/rpcCall.test.ts` and by the live-probe result recorded per method at the call site. **Correction (SHARK-3393 / SHARK-3560, 2026-08-05): this row described the guard that was REMOVED, and described it as the shipped behaviour.** It said `rpcCall` is a default-deny read allowlist and that ten legitimate reads (`web3_sha3`, `net_listening`, `net_peerCount`, `eth_mining`, `eth_hashrate`, `eth_coinbase`, `eth_createAccessList`, `debug_storageRangeAt`, `txpool_content`, `txpool_inspect`) had been re-admitted as exact-match entries. There is no read allowlist any more. The guard is a WRITE DENYLIST only, and everything it does not refuse is FORWARDED to the endpoint. What still refuses locally is the class the proxy forwards rather than judges: transaction broadcast and signing, transaction construction (including Sui's `unsafe_*` builders, which `unsafe_moveCall` used to slip past on the "call" substring), node administration, named node and wallet state mutation, mutating verbs, and the operational half of geth's `debug_` namespace. Which READS exist is decided by the two layers that are current by construction and that a list in this repository can never match: the per-chain blockchain schema in the proxy, which answers `-32075 Method disabled, restricted by blockchain schema`, and the tenant the caller's authenticated session resolves to. So the ten methods above are no longer refused locally, and availability is the proxy's per-chain answer exactly as before (six of the ten answer `-32075` on eth/bsc, as `txpool_status` always has). SHARK-3560 is dissolved along with the mechanism that created it rather than fixed; the test that pinned its refusals now pins the forwarding.

So a key created a moment ago is reachable by naming its slot, on the same connection, with no reconnection, nothing pasted and no credential in the conversation. The 2026-08-07 measurement this ticket started from is what made it worth doing: reaching the chain tools used to cost a second MCP entry, a hand-pasted key and a CLIENT RESTART, and it was the restart that stopped people. **The RAW-key plane at `/rpc` is unchanged and still PARTIAL in the SHARK-3545 sense** — it binds one key at connect, on purpose: a per-call key would ride in the request body, which the per-request key check does not inspect, so a session could be driven with a credential it was never opened with, and that plane has no principal to scope an override against.

Eight of the thirteen +routes are about ONE TEAM and carry the account (`groupSupportedRouter` in the +gateway's `src/route/router.go`, plus a key in the `acl` map of +`src/middleware/groupacl.go`). Five are about the LOGIN — creating a team, seat +eligibility, and the invitee's own list, accept and reject — and sit on the plain +`secureRouter`, where a `?group=` is neither honoured nor rejected but silently +DROPPED.

It takes NO team argument: it reports the team the session was aimed at with `mgmt_select_account`, so it cannot answer about a team the caller did not choose. On a personal account it refuses and says why, in the terms a personal account deserves (it HAS no members, invitations or roles; it is not missing them). Member email addresses are MASKED to one character plus the domain, because a member is addressed by account address on every action here; a pending invitation's address is shown WHOLE because `{email}` is the only handle the cancel and resend routes accept, and masking it would leave a caller able to see an invitation and unable to withdraw it. `_meta` carries masked addresses only, with no exception, because it is the field a host is most likely to log wholesale. A member entry with no address is dropped, counted and reported, never rendered as a member with a blank identity | +| 8.2 | Create a team | **DONE** | Ships in SHARK-3554. `mgmt_create_team` posts `POST /auth/groups/new`, HITL-gated, and `transferAssets` defaults to FALSE. When it is true the approval page changes shape rather than adding a field: the summary line itself reads `... AND TRANSFER EVERY ASSET OF PERSONAL ACCOUNT 0x... TO IT`, naming the account the assets leave, and the effects lead with the two consequences a person cannot infer from the words "create a team" — every asset moves and there is no route here or in the console that moves them back, and the gateway invalidates this login's access token so the next call fails until somebody signs in again. It also states that the transfer does not apply to MetaMask logins. The tool is annotated destructive AND non-idempotent, which needed a fourth annotation class: a second call creates a SECOND team, so claiming idempotence would invite the retry that leaves a customer owning two teams with one set of assets moved. The gateway's OWN `asset_transfer_done` decides what the caller is told, so the 207 case (team created, transfer failed) reports the transfer as not done and says not to retry. The route is on the plain `secureRouter`, so it passes `group: null` and is registered on the raw server: the assets are the login's own, whichever account is selected | +| 8.3 | Know whether I am allowed to create one (seat eligibility) | **DONE** | Ships in SHARK-3554. `mgmt_can_create_team` reads `GET /auth/groups/new/isAllowed`. It answers a TRI-STATE, not a boolean: yes, no, and "the gateway did not say", because a reply this server could not read must not be reported as a refusal.

Only the fields passed are sent, so an omitted field is left alone while an explicit empty string CLEARS it, and the two are not flattened. `TeamRenaming` is OWNER only in the console's map and `PATCH /auth/groups/detail` is OWNER only in the gateway's acl, so the two agree exactly and an admin, developer or finance seat is refused up front with the role and the capability named. The consent page shows the old value beside the new one, and degrades to `(empty) becomes "X"` rather than losing the page when the details read fails. The reply is not read back, so the result says the change was ACCEPTED and names `mgmt_get_team` as the read that settles it | +| 8.5 | Invite teammates | **DONE** | Ships in SHARK-3554. `mgmt_invite_teammates` posts a bare ARRAY to `POST /auth/groups/invite?group=`, HITL-gated, up to 25 addresses per call. The outcome is reported PER ADDRESS and never collapsed: sent, not sent, and a third category for an address the gateway said nothing about, which is treated as unknown rather than sent. An empty results array is NOT read as success (`every()` is true for it). Malformed addresses and a repeated address are refused BEFORE the approval is minted, the second one rather than de-duplicated, because the same person with two different roles is a caller who does not know what they are asking for. Seat pressure is on the approval page (`3 of 4 seat(s) used`, pending invitations counted the way the console counts them), and it INFORMS rather than gates: an invite over the limit fails with the gateway's own reason, because the gateway counts seats against state this shim does not hold | +| 8.6 | Cancel a pending invitation | **DONE** | Ships in SHARK-3554. `mgmt_cancel_invitation` posts `POST /auth/groups/invite/cancel?group= {email}`, HITL-gated. The invitation is resolved from the team's own pending list before the gate on both runs, so an address that names no invitation is refused without costing a human a login and a click, and the approval page can name the person and the role they were invited as. `{result: false}` from the gateway is reported as not done, never as done | +| 8.7 | Resend a pending invitation | **DONE** | Ships in SHARK-3554. `mgmt_resend_invitation` posts `POST /auth/groups/invite/resend?group= {email}`, HITL-gated because it puts an email in somebody else's inbox.

A caller with team A selected who accepts an invitation from team B joins B, and a test drives exactly that arrangement. The caller names the TEAM and the confirmation code is resolved here, so the code reaches neither the transcript, nor the approval binding, nor the consent page. An invitation that is not PENDING is refused with its actual state named, and two open invitations to one team are refused rather than resolved.

With no filter the parameter is absent entirely rather than present and empty. The confirmation code each invitation carries is never rendered, in the text or in `_meta`. About the LOGIN, so the answer is the same whichever account is selected | +| 8.11 | Change a member's role | **DONE** | Ships in SHARK-3554. `mgmt_set_member_role` patches `PATCH /auth/groups/members?group= {user_address, role}`, HITL-gated, `TeamManagement` (OWNER or ADMIN in both the console's map and the gateway's acl). The page says what the new role MEANS rather than only its name, because "ADMIN becomes DEV" is a fact about a string while "can no longer pay" is what a human is approving. **Demoting the team's last OWNER is refused before the approval is minted**, with the reason and the way out (promote somebody else first). A change to the role already held is refused too, so no human approval is spent on nothing. **Setting somebody to OWNER is a TRANSFER and only an OWNER may ask for one, which SHARK-3373 established from the backend rather than from who may call the route.** The route being OWNER-or-ADMIN in the gateway's acl and `TeamManagement` being OWNER-or-ADMIN in the console's map both answer who may CALL it, and neither governs which target role the body may carry nor whether the caller may name themselves; reading either as "an admin may self-promote" is a conflation. multirpc-user-manager settles it: an OWNER appointment from a requestor who is not already an owner is `PermissionDenied` (`actionsProcessorService/service.go:3062-3064`), a requestor naming themselves is `BadRequest` (`service.go:3051-3053`), a target who is already an owner cannot be changed at all (`service.go:3026-3029`), and when it IS allowed every current owner is switched to ADMIN in the same transaction so the team never holds two (`service.go:3068-3085`). None of it is bypassable from here because the gateway sends `ForceExecution: false` (`usermanagerservice.go:1025`). The console mirrors the same split: its role menu offers ADMIN/DEV/FINANCE only and OWNER is reachable solely through the Transfer Ownership dialog, gated on the OWNER-only `TeamOwnershipTransfer` rather than `TeamManagement` — a UI reflection of the backend rule, not a UI-only restriction. **So the shim adds no rule of its own here and forwards the backend's refusal verbatim**, pinned by tests that assert the gateway's own words reach the caller, that no success is claimed, and that the spent approval is reported. The last-owner way-out text was corrected in the same pass: it used to say "make somebody else an OWNER first with this tool", which is a dead end for an ADMIN, who is exactly the caller most likely to reach that refusal and cannot appoint an owner at all. The reply carries the whole team, so the resulting role is READ rather than asserted: a reply that still shows the old role is reported as NOT confirmed | +| 8.12 | Remove a member | **DONE** | Ships in SHARK-3554. `mgmt_remove_team_member` calls `DELETE /auth/groups/members?address=&group=`, HITL-gated, `TeamManagement`. The approval page names the member (account address plus masked email plus current role), the team by name, and the effect in words: they lose the team entirely and immediately, their own personal account is untouched, nothing the team owns is deleted. **Removing the last OWNER is refused before minting.** Removing YOURSELF is allowed, because it is the same operation the gateway performs for "leave", and the page leads with `THAT IS THIS LOGIN`. A details read that fails REFUSES the removal rather than sending it blind, because without the member list there is no way to tell whether it takes the last owner away. A reply that still lists the member is reported as not confirmed | +| 8.13 | Leave a team | **DONE** | Ships in SHARK-3554. `mgmt_leave_team` calls `DELETE /auth/groups/leave?group=`, HITL-gated, and an OWNER gets the role-shaped refusal rather than a 500: `TeamLeaving` is held by DEV and FINANCE and by neither OWNER nor ADMIN, so both are refused by the shared capability pre-flight before the handler runs. **The gateway does NOT enforce that**, which was checked rather than assumed: `DELETE /auth/groups/leave` has an EMPTY role list in the acl map, which the middleware reads as "any member", and the controller hands the decision to a gRPC service that is not part of the accounting gateway. So the shim pre-empts, with a SECOND guard for the case the capability check deliberately fails open on (a role this shim does not model): if the member list shows this login as the only OWNER, leaving is refused with the reason. A details read that fails does NOT block leaving, which is the opposite of the removal above and deliberately so — refusing there would turn an incidental outage into a lock-in. A confirmed leave says the session is still AIMED at that team and must be switched | +| 8.14 | Read the role I hold on a group, and see it in tool output | **DONE** | READING it ships (SHARK-3552): `user_role` arrives per group on `GET /auth/group`, so `mgmt_list_accounts` shows the role held on each team account, and the account echo, the pin confirmation and `mgmt_whoami` name the role in force for the selected team account. The `/confirm` approval page now names it too (SHARK-3553): a gated write on a team account renders `Role on this team account`, supplied from the session's selection in ONE place (`teamRoleInForce` in `src/mgmt/tools/index.ts`, read at mint time in `confirmation.ts`) rather than by each gated tool (**32** of them, pinned as `HITL_GATED_TOOLS` in `test/mgmt-annotations.test.ts`; this row said 15, the count when SHARK-3553 shipped, and the whole point of supplying it once is that the number keeps growing). A role is printed only when the gateway reported one, and never for a personal account, which has none: the field is ABSENT there, so no row is rendered at all. The per-member role from `GET /auth/groups/details?group=` closes it (SHARK-3554): `mgmt_get_team` lists every member with the role they hold, and `mgmt_set_member_role` changes one, with the meaning of the new role spelled out on the approval page. Roles are still team-only everywhere: nothing renders, claims or gates on a role for a personal account, and no refusal implies one is missing | +| 8.15 | Have capability-bearing tools refuse when my role lacks the capability | **DONE** | Ships in SHARK-3553. One in-shim copy of `permissionsMap` (`src/mgmt/tools/rolePermissions.ts`) maps every registered tool to the capability it needs, and a test proves the mapping and the explicit capability-free list partition the registered surface exactly, so a new tool cannot land ungated. Key writes and allowlist writes need `JwtManagerWrite`, key/allowlist reads `JwtManagerRead`, usage reads `UsageData`, balance/invoice/subscription reads `Billing`, card and subscription writes `Payment`, notification DELIVERY settings `TeamNotifications`. The asymmetry a naive gate gets wrong is pinned in both directions: FINANCE has Billing and Payment but not UsageData or JwtManagerRead; DEV has UsageData and JwtManagerRead but neither billing nor write; and TeamLeaving is held by DEV and FINANCE, not by OWNER. Enforced in ONE place (`withAccountScope`), BEFORE the handler and therefore before any approval link is minted, and it costs no request (the role travels with the selection). Refusals name the account, the role, the missing capability, the roles that carry it, and that the gateway remains the authority. It fails OPEN on a role the gateway did not report or one we do not model. NEVER applied to a personal account: no selection means no role, structurally. Unmapped on purpose, rather than guessed: the notification inbox, the price catalogue, card eligibility, identity and account selection | + +--- + +## How to use this file + +1.

Not every +// route we call is on that router. Appending the parameter to a route that +// ignores it is the exact defect this module exists to prevent: the gateway would +// answer for the PERSONAL account while the transcript said the team account. +// Dropping it silently is the same defect wearing a different hat. So a route +// with no evidence REFUSES while an account is in force, and the refusal names +// the limitation. +// +// THE KEY IS `METHOD PATH`, NOT PATH (SHARK-3587). Go registers a handler under a +// METHOD *and* a path, so keying on the path alone lets one verb inherit another +// verb's evidence. The gateway is unambiguous about it in two places, both read +// directly rather than inferred from the console: +// +// 1. `src/route/router.go` registers every route as +// `.Methods(http.MethodX).Path("/y")`, so `/auth/jwt` is on the +// group-supported router for DELETE (router.go:475-477) and for no other +// verb. Under a path key, a GET /auth/jwt would have been treated as +// account-scoped on DELETE's evidence. +// 2. `src/middleware/groupacl.go:579` builds its own lookup key as +// `fmt.Sprintf("%s %s", r.Method, r.URL.Path)`. Our key is now the same +// shape as the gateway's own, minus its `/api/v1` prefix. +// +// So the entries below are `" "`, exact-match, and no prefix and no +// sibling verb can widen one by accident. +// +// WHAT MAKES A ROUTE ELIGIBLE. Two gates, both in the gateway, and a route needs +// BOTH: +// +// GATE 1 (router.go) the route is registered on `groupSupportedRouter` or its +// child `groupSupportedMfaRouter` (router.go:250-256). A route on +// `secureRouter`/`secureMfaRouter` never sees `groupAclMiddleware`, so a +// `group` parameter is not rejected there — it is SILENTLY IGNORED and the +// gateway answers for the account the credential owns. That is the +// wrong-account disclosure, and it is why absence from this set must mean +// refusal and never "send it anyway". +// GATE 2 (groupacl.go) the `" /api/v1"` key exists in the `acl` +// map. A group-supported route MISSING from that map does not leak: the +// middleware logs "method rules not added" and returns HTTP 400 +// `invalid_argument` (groupacl.go:591-597). Loud, not silent, but still a +// broken call, so we do not allowlist those either. As of the commit named at +// the end of this header, exactly two group-supported routes fail gate 2 and +// this shim calls neither: `GET /auth/referral/referrals/count` (the acl map spells it +// `/auth/referral/numbers`) and `GET /auth/stats/users/{token}/requests/{period}` +// (matched only by the `endpointsWithPathParamAcl` glob, which the exact-key +// lookup misses first). +// +// ABSENCE FROM THE SET IS NOT AN OPT-OUT, AND THIS IS THE TRAP OF THIS MODULE +// (SHARK-3586). A route merely left out of the set still INHERITS the session's +// selection in `resolveGroup`, so under any selected team account `request()` +// raises `AccountScopeError` and every tool over that route refuses. There are +// therefore THREE outcomes a route can have, not two: allowlisted below, or an +// explicit `group: null` at its call site in `gateway/client.ts` meaning "this +// route is not about one account", or a refusal. The blocks below record which +// applies per route, and why. `test/mgmt-account-scope-completeness.test.ts` +// walks every method on the real client and pins each one as scoped, opting out, +// or refusing, so a route cannot land in a silent fourth class. +// +// MFA IS ORTHOGONAL TO THE ACCOUNT QUESTION. +// `groupSupportedMfaRouter` is created as a CHILD of `groupSupportedRouter` +// (router.go:253), so it inherits `groupAclMiddleware` and only ADDS +// `mfaMiddleware`. Being MFA-gated therefore says nothing about whether a route +// takes the account: `PATCH /auth/whitelist/mode` and `POST +// /auth/payment/cancelSubscription` are both MFA-gated AND account-scoped. +// Conversely `secureMfaRouter` (router.go:245) is a child of `secureRouter`, so +// the platform-key trio is MFA-gated and NOT account-scoped.

A session +// belongs to the LOGIN, not to an account: the same person signed in on the same +// laptop is one session no matter which team account this session happens to be +// aimed at, and `?group=` has nothing to select. That makes these routes the +// same shape as `/auth/2fa/status` (tools/twoFactor.ts) and they get the same +// treatment — registered on the RAW server, stating plainly that the subject is +// the login, and NOT refused while a team account is selected. Refusing would +// deny a customer the incident-response control for no gain, and appending a +// parameter the route does not model would be the defect this file prevents. +// +// THEY OPT OUT WITH `group: null` in `gateway/client.ts`, not by staying out of +// the set above (SHARK-3586; see "absence from the set is not an opt-out" in the +// header).

Destructive, financial and alert-suppressing " + + "tools cannot be completed by this model alone. Call the tool WITHOUT " + + "`confirmToken` and it returns an approval link plus a token. A human opens " + + "the link, signs in as the same account, reads a consent page naming the " + + "action, the object and the effects, and submits it. You then re-run the SAME " + + "tool with the SAME `confirmToken` and the same arguments. A token is " + + "single-use, expires in 5 minutes, is bound to the account and to the " + + "arguments, and cannot be minted or approved by this model. `confirm` is a UX " + + "affordance ONLY and is never a security boundary. Some tools are gated only " + + "for some arguments; those say so in their own description.\n\n" + + "2. SECOND FACTOR. Six gateway routes are protected by two-factor " + + "authentication. On an account that has it enabled, the APPROVAL PAGE asks " + + "the human for the current 6-digit code and carries it into the write; the " + + "code never reaches this model, the transcript, `_meta` or a log. Never ask " + + "the user to type a 2FA code into the conversation. The `totp` argument exists " + + "for a caller that genuinely holds a code and is normally left empty. This " + + "server only forwards a code; the gateway verifies it.\n\n" + + "3. `expectAccount`. Optional on every account-scoped tool. Pass the account " + + "address you believe this session acts on, as mgmt_whoami reports it. If the " + + "session is aimed at a different account the call is REFUSED, both addresses " + + "are named, and nothing is sent to the gateway. Use it on anything you would " + + "not want applied to the wrong account. mgmt_pin_account does the same for a " + + "whole session.\n\n" + + "4. WHAT A REPLY MEANS. A tool says a thing happened only when it observed it. " + + "`Done:` means the result was read back. Wording about a request being " + + "ACCEPTED means the gateway returned 2xx and the resulting state was NOT " + + "observed, with the read tool that can settle it named.

An + // agent whose client renders instructions never has to spend a call to learn + // the sets exist; an agent whose client drops or truncates them still has the + // tool in its list. Either route is enough on its own, which is what makes the + // narrowed default safe. + // SHARK-3609: the second half of this contract must name the TOOL CALL, not the + // reconnect URL. On an OAuth-gated server a reconnect means re-running + // discovery, re-registering and re-authorising to reach one more tool, and an + // instruction that offers only that URL is what sends an agent down it. + "5. TOOL GROUPS. This connection registers only the groups it asked for, so a " + + "tool you expect may simply not be loaded. Groups: core (always on, cannot be " + + "dropped), data (blockchain reads: balances, blocks, logs, transactions, " + + "token prices, contract resolution and a generic rpcCall), keys, usage, " + + "billing, notifications, team, identity. If a tool you " + + "need is missing, call mgmt_load_toolset with the group that holds it: it is " + + "registered in THIS session, your tool list is updated and no reconnection or " + + "re-authentication happens. Do not reconnect for this. `?toolsets=` on the " + + "MCP URL still sets what a NEW connection starts with, comma-separated (for " + + "example `?toolsets=core,keys,billing`) or `all`; with no parameter you get " + + "core and data. Call mgmt_list_toolsets for each group's size and cost.\n\n" + + // SHARK-3629.

Eleven tools addressed a key by its ENDPOINT TOKEN, the live +// credential in rpc.ankr.com//, and mgmt_list_api_keys redacts that +// on purpose. So freezing a key you did not create in the same session took TWO +// human approvals: one for mgmt_reveal_api_key, to get the token, and one for +// the freeze itself. That is not friction, it is the wrong shape: +// +// - THE SAFER ACTION REQUIRED PERFORMING THE MORE DANGEROUS ONE FIRST. +// Freezing is reversible and destroys nothing. Revealing hands a live RPC +// credential to the model and leaves it in the transcript, where it stays. +// - It inverted what the human was asked. The first consent page asked to +// reveal a secret — the request with real blast radius — and the person +// clicked it as a step towards a benign one. That trains people to approve +// reveals. +// - It multiplied: N keys meant N permanent credential disclosures. +// +// THE FIX. The token is resolved INSIDE the shim, from the slot index the +// listing already shows, and never emitted. One approval, on the action the +// human actually wants, naming the key by slot and name rather than by a secret. +// +// WHY THE SHIM CAN DO THIS AT ALL. Turning a `jwt_data` into an endpoint token +// needs the console's worker gateway, which sounds like a service this shim has +// no client for. It has had one since mgmt_reveal_api_key shipped (SHARK-3541), +// and the worker takes no Authorization header at all — possession of a valid +// `jwt_data` IS the capability (gateway/worker.ts). So the resolution below is +// the reveal's own two steps with the last one, the part that publishes the +// credential, removed. +// +// WHAT RESOLVING COSTS, STATED PLAINLY. Naming a key by slot buys one extra +// gateway read (`GET /auth/jwt/all`, which most callers have already made) and +// ONE worker exchange, per call. The exchange is the console's own +// (`POST /api/v1/jwt {jwtToken, createNew:"yes"}`) and the worker treats it as +// idempotent for a key it has already imported. +// +// It matters that this now happens from tools annotated read-only, because +// USER-STORIES row 3.4 recorded a decision NOT to run it from one: that decision +// was about mgmt_get_spending_breakdown, where pairing every masked token in a +// listing with a name would have meant N exchanges from a single cheap read, +// unbounded by anything the caller said. This is the bounded case — at most one +// exchange, for the one key the caller named, the same call the equivalent write +// would make — and a read still returns no credential of any kind. If the worker +// ever stops being idempotent here, that is a fact about mgmt_reveal_api_key +// first and about these tools second, and both are wrong together rather than +// this being the surprising one. +// +// WHAT DOES NOT CHANGE. +// - mgmt_reveal_api_key stays exactly as it is, for the case where a human +// genuinely wants the credential. +// - `token` is still accepted, and is documented as deprecated. Callers exist, +// and every one of these schemas is `.strict()`, so an undeclared key is +// refused rather than ignored. +// - The resolved token is what the approval is BOUND to.

The acceptance criterion asked for it HITL-gated, with a +// consent page stating what a bind grants. The consent page cannot state that, +// and the reason is in the route's own signature: the console calls it +// `bindOauthAccount(body: IOauthSecretCodeParams)`, and that body is +// `{secret_code, state, provider?}` — an OAuth authorization code and the CSRF +// state from the provider's redirect. The identity being granted access lives +// INSIDE that opaque code and only the gateway can decode it, so the page +// would have to read: "grant an unnamed account permanent login access to +// yours". A consent page that cannot name the subject of the grant is not +// consent, and this is the single most privileged write on the surface — more +// than a Platform API key, which at least expires. +// +// Two lesser reasons, either of which would be enough on its own. The code +// cannot be obtained from here: the flow starts at `GET /oauth2/getProviderParams` +// and the provider redirects to the URL the gateway hands back, which is the +// console's, and the console consumes the code the moment it lands. And a +// `secret_code` argument would teach an agent to ask a user to paste an OAuth +// code into a chat transcript, which is the same defect tools/twoFactor.ts +// refuses to ship for TOTP codes. +// +// What ships instead: mgmt_list_login_methods states plainly what a bind +// grants, folds in `GET /auth/abstractBindings/available` so a caller can see +// which kinds CAN be bound and whether binding is open at all, and says where +// binding is done. Wiring the real thing later means building a second, +// provider-facing OAuth leg with an overridden `redirectUrl` pointing at this +// server, plus a gateway-side entry for that URL. That is a feature, not a +// line, and it is recorded on the ticket rather than half-shipped. +// +// 2. EMAIL IDENTITY WRITES ARE DEFERRED, and the split is stated here so neither +// ticket assumes the other did it. This ticket ships the two READS +// (`GET /auth/email`, `GET /auth/email/active`). NOT shipped here and NOT +// shipped by the notification-channel work either: `POST /auth/email/bind`, +// `PATCH /auth/email/bind`, `DELETE /auth/email/bind`, `POST +// /auth/email/confirm` and `POST /auth/email/resendConfirmation`. +// +// They are a different thing from the notification email, and the two are easy +// to confuse because both are "an email on the account": `POST +// /auth/notifications/email/enable` (already shipped as +// mgmt_add_notification_email) adds a DELIVERY channel for alerts, while +// `/auth/email/bind` changes a LOGIN IDENTITY. The deferral is deliberate: +// the chain only completes when a code delivered to the mailbox is posted back +// to `/auth/email/confirm`, which is a second out-of-band secret the agent +// would end up holding, and `DELETE /auth/email/bind` is a second lockout path +// that needs the same last-method treatment the unbind gets below. All three +// bind verbs are `true` in mfa.go's targetList, so they are second-factor +// routes as well. +// +// --------------------------------------------------------------------------- +// THE LAST-METHOD DECISION (the recorded choice the ticket asked for): REFUSED. +// --------------------------------------------------------------------------- +// An unbind that would leave this login with NO bound login method is refused by +// name, before any human is asked to approve anything, and the refusal says it +// is this server's rule rather than the gateway's. +// +// The alternative the ticket offered — allow it, with the consequence spelled out +// on the consent page — is what SHARK-3577 chose for self-revocation, and the +// difference is worth stating because the two look alike. Ending your own session +// has a real incident-response use: if the leaked credential IS this session's +// bearer, a tool that will not kill it is useless in the one incident it exists +// for. Removing your LAST way in has no such use. An account taken over by +// someone who bound their own login is fixed by unbinding THEIRS, which this tool +// does. There is no situation in which a customer urgently needs to be left with +// nothing, so the refusal costs a trip to the console, while allowing it costs an +// account nobody can sign into and a support ticket to get it back. +// +// The check is honest about its denominator: it counts the bindings on `GET +// /auth/abstractBindings/list`, it says so, and it says what it cannot see. An +// entry the gateway returned that could not be read is counted and declared. +// +// SEPARATELY AND FIRST, the gateway's OWN verdict is honoured. Every binding +// carries `canUnbind` and `canUnbindReason`, and the console disables its +// disconnect button on exactly those two fields.

Neither INITIATOR is on the gateway's MFA subrouter (both are +// on groupSupportedRouter — verified in route/router.go), so for those two `totp` +// is optional and accepted for call-site symmetry only; they do not forward it, +// because a non-MFA route would ignore x-ankr-totp-token anyway. +// cancelSubscription IS on that subrouter, so it DOES forward `totp` as +// x-ankr-totp-token, exactly as the key-delete and allowlist-edit writes do.

"Log in from a client without pasting a token" was recorded as +// an OAuth-only story, so the surface looked like it had no answer for CI beyond a +// browser login. The console has had one all along: Settings -> Platform API mints +// a bearer for the accounting gateway itself, over three routes read at +// w3tech/web3api-frontend fe773bd (see gateway/client.ts for the inventory and the +// wire quirks). Not wiring it left a real capability silently missing, which is +// the one status USER-STORIES.md refuses to carry. +// +// HOW THIS CREDENTIAL DIFFERS FROM EVERY OTHER ONE ON THIS SURFACE, and why the +// gate and the wording are as heavy as they are. An RPC endpoint token +// (mgmt_create_api_key, mgmt_reveal_api_key) spends the account's quota: bad, and +// bounded. A PLATFORM API key is a bearer for the management API, so it carries +// the whole of THIS surface: minting and deleting keys, editing allowlists, +// reading billing, starting a payment. It is also the one credential here that +// bypasses this shim's own gate, because a holder does not need the shim at all. +// So: +// +// - the mint is HITL-gated, and the consent page says in plain words that the +// thing being approved can act without any further human approval; +// - the TTL is bounded by the schema at one year, the longest the console itself +// offers (its dialog offers one month, six months and one year), and is shown +// to the human in days rather than as a second count; +// - the bearer is delivered exactly ONCE, in the mint reply, and never enters a +// log, `_meta`, a consent page, an error message or the listing. The listing +// is a PROJECTION of four fields for that reason, not a pass-through; +// - the revoke is HITL-gated and states its own irreversibility. +// +// ACCOUNT SCOPE. None of the three routes carries `?group=` (the console passes no +// params object to any of them), so a platform key belongs to the account whose +// credential minted it.

NO CLIENT IP AND NO LAST-SEEN. The listing was specified to name "device, +// IP and last seen". `IGetAllSessionsResponse` carries neither an IP nor a +// last-used timestamp — its only two instants are `created_at` and +// `expires_at`, and its only client facts are the five `creation_details` +// fields (os, os_version, browser, browser_version, device). Printing +// `created_at` under the heading "last seen" would be a fabricated security +// fact on the exact screen where a customer decides which login is the +// intruder, so the tool states that both are absent instead. +// +// 2. `POST /auth/session/ui/logout` IS NOT WRAPPED. `mgmt_logout_other_sessions` +// was specified as a wrapper for it. On the console's gateway class that +// route is `logoutCurrentSession()` — its name says it ends the CURRENT +// session, the opposite of what the tool is for — and NOTHING in the console +// calls it. The console's own "Terminate all other sessions" button is +// `deleteSessions({token_keys: })` +// (useTerminateButton.ts, same commit). With no call site and no vendored +// gateway source, there is no evidence for either reading of that route, and +// a security control whose blast radius is a guess is worse than no control. +// So `mgmt_logout_other_sessions` does exactly what the console does, over +// the delete route, and the logout route stays unwrapped. +// +// 3. SELF-REVOCATION IS ALLOWED, WITH THE CONSEQUENCE ON THE CONSENT PAGE (the +// recorded choice the ticket asked for). The console REFUSES it: pressing +// terminate on your own row opens a dialog that terminates all the OTHER +// sessions instead. We diverge deliberately, and the reason is the whole +// point of the ticket. A console user who wants to end their own session has +// a logout button three inches away; an MCP caller has nothing. If the leaked +// credential IS this session's bearer, a tool that refuses to kill it is +// useless in the one incident it exists for. So it is allowed when the caller +// names that one session explicitly, the approval page leads with "this signs +// this assistant out", and the human who will be signed out is the human +// reading that sentence. It is never a side effect: `mgmt_revoke_session` +// takes ONE session, and `mgmt_logout_other_sessions` will not run at all +// unless it can positively identify the current session to spare. +// +// --------------------------------------------------------------------------- +// THE HANDLE IS TREATED AS A CREDENTIAL AND NEVER RENDERED. +// --------------------------------------------------------------------------- +// The evidence says `token_key` is a handle, not a bearer: the sibling +// /auth/token/custom/* routes return `access_token` for the secret and +// `token_key` for the handle, and this route hands one out for EVERY session, +// which no API does with live bearers. But "the evidence says" is not "we +// verified" — the gateway source is not vendored here — and being wrong means +// publishing the bearer of every device the customer owns, into a transcript, on +// the screen they opened because they think they were breached. +// +// So the handle never leaves this module. Sessions are addressed by a +// SESSION REF: `s-` plus eight hex characters of a keyed digest of the handle. +// It is one-way, it is stable for the life of this server process (long enough +// for a list-then-revoke conversation), and the key is random per process, so a +// ref is not a value anyone can precompute, correlate across deployments, or +// walk back to a handle even if the handle turns out to be low-entropy. A ref +// that no longer resolves is a refusal, never a guess. +// +// ACCOUNT SCOPE. Neither route takes `?group=`, and unlike the platform-key +// trio the tools do NOT refuse under a team account: a session belongs to the +// LOGIN, so there is no per-account answer for the parameter to select. The +// per-route evidence and that reasoning are recorded in gateway/groupScope.ts. +// For the same reason all three register on the RAW server, like +// mgmt_get_2fa_status: the account-scope wrapper would append "Account: 0x..." +// to an answer that is not about an account. +// +// SHARK-3586: saying that takes more than leaving the two routes out of +// GROUP_SUPPORTED_ROUTES — see "absence from the set is not an opt-out" in +// gateway/groupScope.ts.

Rendering this map verbatim would put EVERY key on the account into a +// transcript from an unapproved tool that a host has been told is read-only. That +// is not a leak at the edges, it is the reveal gate defeated by reading a usage +// endpoint.

That +// is the subject of the block above `registerSetMemberRole` below; +// - none of it is bypassable from this surface: `force` is what skips those +// checks, and the gateway's client hard-codes `ForceExecution: false` +// (usermanagerservice.go:1025). +// +// LEAVING IS THE ONE THAT IS STILL OPEN. `DELETE /auth/groups/leave` carries an +// EMPTY role list (groupacl.go:275), which the middleware reads as "any member" +// (groupacl.go:614-617), and no owner guard was found on its service path.

It is the PARAMETER that only +// subtracts, and a RESOLVED selection that cannot be mutated. A live +// session can now GROW, through mgmt_load_toolset, which registers a group +// in place and notifies the client (tools/loadToolset.ts). That is a +// separate object with its own type — see createSessionToolsets below — so +// the immutable resolution keeps its guarantee and no code holding one can +// widen a session by accident. +// +// WHY WIDENING IS SAFE. The selection is not an authorization boundary; it +// is a +// context-cost control. Every tool keeps its own gates: the HITL +// confirmToken on destructive, financial and alert-suppressing writes, the +// role mirror and account-scope check in withAccountScope, and the +// gateway's own second factor on the six routes it fronts. Loading a group +// changes what is ADVERTISED, never what is PERMITTED, and every one of +// those tools was already reachable by reconnecting with a wider +// `?toolsets=`.

Option A (a per-call key argument, or a +// rebind tool) was REJECTED on the evidence, and the reasons are pinned as tests +// below rather than left in a commit message: +// +// 1. The bound key IS the data plane's session identity. src/http.ts boundKeyOk() +// re-derives the key from the x-ankr-api-key header / Bearer on EVERY +// POST/GET/DELETE and constant-time compares a salted hash against the one +// recorded at initialize. That is the whole of the SHARK-3382 fix. +// 2. A per-call `key` argument travels in the JSON-RPC BODY, which boundKeyOk +// does not and cannot inspect. The transport check would pass on the header +// while the upstream call went out on a different credential: SHARK-3382's +// tests would stay green while the property they defend ("a session cannot be +// driven with a credential other than the one it was bound to") was dead. +// That is weakening the guarantee in substance, which is exactly what the +// bias in the ticket rules out. +// 3. Option A's own acceptance criterion, "the override cannot be used to reach +// a key the authenticated principal does not own", is unimplementable in this +// image: the data plane never authenticates anybody. It passes the caller's +// key through to rpc.ankr.com and lets Shark decide. There is no principal +// to scope an override against, and the two planes ship as separate images +// with no shared session state. +// 4. TorpcClient.apiKey is `private readonly`, injected once via +// createServer(key) -> buildProvider / buildTorpcClient, and its constructor +// comment records that the env fallback was deliberately removed "so a future +// caller can never silently inherit the server's ambient key instead of the +// caller's key". A per-call override reintroduces precisely that ambiguity. +// 5. A credential in every tool call argument lands the key in the transcript on +// every call, instead of once on a gated, human-approved reveal. +// +// SO WHAT IS PINNED HERE is the honest contract, at all three places a caller +// actually meets the limit: the reply that hands over a usable key, the data +// server's own session-level self-description, and the refusal a caller gets if +// they try to drive an open session with the new key.

A customer who +// believed their credential had leaked could not enumerate their logins from +// here, could not kill one, and was not told the console has a screen that can. +// That lands hardest on us specifically: a management-MCP session IS one of the +// logins in that list, so the agent holding a stolen bearer and the customer +// trying to revoke it are looking at the same row. +// +// THREE OF THE TICKET'S ACCEPTANCE CRITERIA WERE NOT TRUE OF THE PRODUCT, and +// this file pins the honest alternative rather than the criterion: +// +// - the listing was to name "device, IP and last seen". The route carries +// NEITHER an IP nor a last-used time (`IGetAllSessionsResponse` at +// w3tech/web3api-frontend fe773bd is exactly token_key / created_at / +// expires_at / current_session / creation_details). So the tests below assert +// the tool SAYS both are absent, and assert no IP-shaped string is ever +// rendered — printing `created_at` as "last seen" would be a fabricated +// security fact on the screen where a customer picks out the intruder; +// - `mgmt_logout_other_sessions` was to wrap `POST /auth/session/ui/logout`. +// That route is `logoutCurrentSession()` on the console's own gateway class, +// its name says it ends the CURRENT session, and nothing in the console calls +// it.

So there is a test that asserts the +// logout route is NEVER contacted; +// - self-revocation had to be refused or allowed-with-consequence, and the +// choice recorded. It is ALLOWED. The console refuses it, and we diverge on +// purpose: a console user has a logout button three inches away, an MCP +// caller has nothing, and if the leaked credential IS this session's bearer +// then a tool that will not kill it is useless in the one incident it exists +// for. The tests pin the consent page leading with "signs this assistant out" +// and pin that the bulk logout can never do it as a side effect. +// +// AND ONE INVARIANT THAT IS THE REASON THE REFS EXIST. `token_key` is treated as +// credential-grade and never rendered.

The DEFAULT fits a stated budget. A saving nobody measured is a saving +// nobody made, so the budget is asserted, not described, and the measured +// number is printed next to it. SHARK-3629 moved that default from `core` +// to `core` plus `data` — an endpoint that could not read a chain was the +// wrong thing to serve a connection that asked for nothing — and moved the +// budget with it. The property being held is unchanged: a connection that +// names nothing pays a bounded, measured entry cost, not the whole surface. +// 2. `all` is EXACTLY the pinned surface. The parameter may only ever +// SUBTRACT: if a future tool could join `all` without the pinned list +// moving, the whole security argument below is unenforced. +// 3. Selection does not change any TOOL. The definition a caller sees for a +// tool present in both a limited and a full session must be byte-identical, +// which is what makes "gating is per tool and unrelated to registration" +// checkable rather than asserted in prose. The HITL gate, the second-factor +// policy and the `expectAccount` argument all live in those definitions and +// in the handlers behind them. +// 4. A gated write is still gated in a limited session, per gated category. +// 5. An unrecognised name FAILS the initialize. A lenient fallback over an +// open set silently mislabels every future member of the set, so the +// failure is the feature. The error names the valid set and never echoes +// the input back. +// 6.

Importing the management server does not load it. +// 2. Building a `?toolsets=core` session does not load it. This is the case +// the whole change exists for: an account-administration session pays +// nothing for a tokenizer it will never reach. +// 3. Building the DEFAULT session (core plus data) DOES load it — proving the +// deferral is a deferral and not a removal, and that the cost lands at +// registration rather than inside the first tool call. +// 4. The raw-key data plane loads it at construction, exactly as before. Its +// own header argues for eager loading and that argument is still right +// there: every /rpc session reads chains. +// 5.
